⚠️ experimental feature

jackson•2y ago

need more info

rapid•2y ago

ok so basically it sends a request and gets the json from it and then returns it as a svg that uses the json it works on localhost but it takes a second to load, it might be because Im literally doing it in flask

jackson•2y ago

probably going to need to see some code, not much i can do just based on that

rapid•2y ago

Its a lot but this is the route

@app.route("/picture/<id>")
def discord_presence(id):
    try:
        id = int(id)
    except ValueError:
        return jsonify({"error": "Please provide a valid ID"})
    url = requests.get(f"https://presence.dark.bio/{id}")
    try:
        if url.status_code == 200:
            response = url.json()
            svg = render_presence(response)
            return svg, 200, {'Content-Type': 'image/svg+xml'}
        else:
            return jsonify({"error": "User not found, join discord.gg/darkbio"})
    except Exception as e:
        print(e)
        return(e)

@app.route("/picture/<id>")
def discord_presence(id):
    try:
        id = int(id)
    except ValueError:
        return jsonify({"error": "Please provide a valid ID"})
    url = requests.get(f"https://presence.dark.bio/{id}")
    try:
        if url.status_code == 200:
            response = url.json()
            svg = render_presence(response)
            return svg, 200, {'Content-Type': 'image/svg+xml'}
        else:
            return jsonify({"error": "User not found, join discord.gg/darkbio"})
    except Exception as e:
        print(e)
        return(e)

jackson•2y ago

server invite link lmao anyways

rapid•2y ago

yea 😭 then it goes to a def render_presence(response) and thats really big 137 lines long

jackson•2y ago

how is this deployed? also how do you initialize your flask app

rapid•2y ago

wdym how is it deployed? I mean its through a github repo initialize as in run?

jackson•2y ago

yeah but like do you have a dockerfile, railway.json, etc

rapid•2y ago

nah

jackson•2y ago

yeah how do you configure it in main.py

rapid•2y ago

http_server = WSGIServer(('0.0.0.0', int(os.environ.get('PORT', 8080))), app)
http_server.serve_forever()

http_server = WSGIServer(('0.0.0.0', int(os.environ.get('PORT', 8080))), app)
http_server.serve_forever()

jackson•2y ago

also are there any logs when it fails to return a response

rapid•2y ago

to run it no

rapid•2y ago

rapid•2y ago

js this but it doesnt actually render it

rapid•2y ago

jackson•2y ago

does it sometimes take >60s to return a response? i see 99.xxx and i suspect that might be return time in seconds

rapid•2y ago

it doesnt even return it, it just loads until it times out what

jackson•2y ago

in the logs

rapid•2y ago

yeah it takes more than 60 seconds to return a response in the logs I believe But its quick on localhost

jackson•2y ago

yeah so if it does that railway will drop the request essentially

rapid•2y ago

oh ok, so what can I do to fix it

jackson•2y ago

i'd first try adding some logging around svg = render_presence(response), assuming that it actually runs and works fine there may be issues with returning a huge image in a response body

rapid•2y ago

ok let me try

rapid•2y ago

so I added some logging, well a lot but its timing out with cloudfalre

rapid•2y ago

now also

rapid•2y ago

rapid•2y ago

nothing is being printed to console @jackson can someone help?

Adam•2y ago

This server’s help is provided by the community, please be patient

Brody•2y ago

go back to the basics, add a simple /health route and have it return a 200 code first

Adam•2y ago

Before doing that I would check to see if your app is working with a Railway provided domain rather than a custom one There can be a variety of issues with custom domains that aren’t related to your app’s code but the connection process

rapid•2y ago

doesnt work with custom, or provided mbmb different routes work

Adam•2y ago

Oh you’re the dark.bio guy, I remember checking out your site wasn’t it working a couple days ago?

rapid•2y ago

so rn the api itself works so https://presence.dark.bio/745421881594871939 but if you add /picture/{id} then thats what breaks it renders a svg looks like this

rapid•2y ago

Adam•2y ago

hmm gotcha where are you doing this rendering?

rapid•2y ago

so I pass the response from the api to a def like ths

@app.route("/picture/<id>")
def discord_presence(id):
    try:
        id = int(id)
    except ValueError:
        return jsonify({"error": "Please provide a valid ID"})
    url = requests.get(f"https://presence.dark.bio/{id}")
    try:
        if url.status_code == 200:
            response = url.json()
            print("Before try")
            try:
                print("got into try")
                svg = render_presence(response)
            except Exception as e:
                print(e)
            print("after try before return")
            return svg, 200, {'Content-Type': 'image/svg+xml'}
            print("after return")
        else:
            return jsonify({"error": "User not found, join discord.gg/darkbio"})
    except Exception as e:
        print(e)
        return(e)

@app.route("/picture/<id>")
def discord_presence(id):
    try:
        id = int(id)
    except ValueError:
        return jsonify({"error": "Please provide a valid ID"})
    url = requests.get(f"https://presence.dark.bio/{id}")
    try:
        if url.status_code == 200:
            response = url.json()
            print("Before try")
            try:
                print("got into try")
                svg = render_presence(response)
            except Exception as e:
                print(e)
            print("after try before return")
            return svg, 200, {'Content-Type': 'image/svg+xml'}
            print("after return")
        else:
            return jsonify({"error": "User not found, join discord.gg/darkbio"})
    except Exception as e:
        print(e)
        return(e)

none of the prints have been printing it might be overloading or something but.. it does seem to work on localhost

Adam•2y ago

For one I see a hell of a lot of bad practice But i’ll dig into it, what’s the repo link?

rapid•2y ago

yeah I've never done this kinda shit its private, I can invite you to it

Adam•2y ago

Gotcha, my username is ItsGoldeneyes

rapid•2y ago

ok, btw be ready that it is NOT built well LMAO

Adam•2y ago

Yeah no worries lol chances are that’s probably the issue though

rapid•2y ago

you want the repo link

Adam•2y ago

Nah I got it from the email invite

rapid•2y ago

oh btw some stuff might be extra weird because I used chatgpt to try and help make it faster

Adam•2y ago

No worries, it's readable at least

rapid•2y ago

LOL

Adam•2y ago

What's an id I can use to test?

rapid•2y ago

mine 745421881594871939 or if you want to use your own, you have to join the server oh btw the constants is for the discord commands that are for something else, hence why they're commented out

Adam•2y ago

I think the reason why it's not returning anything correctly may be because of all the try except checks you're doing Those are really bad practice, I'll push a pr to correct that section of the code

rapid•2y ago

ok, let me know then how come its not even printing?

Adam•2y ago

I'm only seeing one print statement

rapid•2y ago

really?? holdon

rapid•2y ago

Adam•2y ago

under get_presence yes

rapid•2y ago

Adam•2y ago

Oh whoops I was changing the wrong function lmao

rapid•2y ago

oh.. is that where he meant logging

Adam•2y ago

Lots of try except everywhere

rapid•2y ago

I think they're only in the discord commands theres none in the render_presence but theres 2 in the routes 3*

Adam•2y ago

Pushed a commit that should help you out Whoops meant to make a pr but I just merged into main

rapid•2y ago

thats fine, lets see if it works automatic server error https://presence.dark.bio/picture/745421881594871939 ima look in the deploy logs there are literally 0 logs oh nvm user not found but im in that server.. nothing got returned in jsonify tho

Adam•2y ago

pushed a commit to print the request so you can see what's in it

rapid•2y ago

alr, so its because url.status_code != 200 thats whats happening it has something to do with the api.. https://presence.dark.bio/745421881594871939 isnt returning anything except return("user not found")

Adam•2y ago

I haven't used the Discord api in a while, is the guild correct?

rapid•2y ago

it cant find me in my own guild tf

Adam•2y ago

Maybe it should be a string instead of an int?

rapid•2y ago

but its printing my guild name what should

Adam•2y ago

The guild id

rapid•2y ago

thats how its supposed to be because it does print my guild name let me make it print the id ok so the guild_id is right and it can find the guild but it doesnt seem to find the id let me try making it int(user_id)

Adam•2y ago

Oh yeah that's my mistake

rapid•2y ago

ok so its supposed to be member = guild.get_member(int(user_id))

Adam•2y ago

does it have to be an int?

rapid•2y ago

yeah, doesn't seem to work if its not.. let me try str

Adam•2y ago

It was str before

rapid•2y ago

yea user not found fr?

Adam•2y ago

I pushed a fix

rapid•2y ago

iht ight

Adam•2y ago

I mean from what I did https://discordpy.readthedocs.io/en/stable/api.html?highlight=get_member#discord.Guild.get_member

rapid•2y ago

I think below it also has to be int like where the picture route is

Adam•2y ago

Good point https://presence.dark.bio/745421881594871939 is working now

rapid•2y ago

ha, works I think yeah add /picture

Adam•2y ago

It's thinking

rapid•2y ago

you can now see what I mean by loading for a long time 😭 ill lyk what logs appear

Adam•2y ago

If it's going to take a while to render then your best option would be to rework it so that request is sent to another service that just renders the images And have your current service display a "waiting for image" message until it recieves a response

rapid•2y ago

hmm, what do you mean so I could add the presence api to dark.bio and then make that entire application just be the image idk if it would wrok though

rapid•2y ago

rapid•2y ago

so it cant find my id so let me try sometihng oh

rapid•2y ago

rapid•2y ago

its already int weird.. btw it works on localhost so wait nvm, stopped working..

Adam•2y ago

No, just make a third service that only processes render requests

rapid•2y ago

what do you mean

Adam•2y ago

When the user requests a /picture then they're given a screen that displays that the server is waiting for the render

rapid•2y ago

idk im confused

Adam•2y ago

Then once that request is finished the page is updated with the image that was created

rapid•2y ago

how would this be

Adam•2y ago

wdym

rapid•2y ago

ok so the first service is the api

Adam•2y ago

It would be a separate service that only creates the image

rapid•2y ago

in a route?

Adam•2y ago

the presence API sends a request to that service to create an image and the service returns that image when it's done processing

rapid•2y ago

im sorry im kinda slow ok so

Adam•2y ago

In the meantime the user is served a page that tells them that the rendering is in progress

rapid•2y ago

yea

Adam•2y ago

Once the rendering is done, the user is shown the image

Brody•2y ago

sorry to chime in here, but how long does picture/<id> take to return when running this on your local machine?

rapid•2y ago

when it works, maybe a second or two im getting status 203 I mean 503

rapid•2y ago

rapid•2y ago

it took around 10 seconds to get user not found though on my machine

Adam•2y ago

What service is handling the user not found request?

rapid•2y ago

/picture/<id> right because thats where the print for the response is

rapid•2y ago

rapid•2y ago

that is getting hit thats good though

Adam•2y ago

Pretty sure you're getting rate limited

rapid•2y ago

idk

Adam•2y ago

By service I mean what's handling the presence.dark.bio/id call Because that's what's returning 503

rapid•2y ago

I feel so stupid uhmm

Adam•2y ago

It's all in the same service right? The only API you're reaching out to is the Discord API?

rapid•2y ago

yes yes

Adam•2y ago

Definitely think you're getting rate limited

rapid•2y ago

actually no

Adam•2y ago

At least with those 503s

rapid•2y ago

I don't think I access the discord api at all..

Adam•2y ago

You 100% do

rapid•2y ago

well because I use stuff from discordpy like the bot does it if yk what I mean

Adam•2y ago

That's just a wrapper for the discord api

rapid•2y ago

oh lmao 💀 so would a discord gateway better better?

Adam•2y ago

No, you'll just have to wait a bit to do more testing

rapid•2y ago

do you know the rate

Adam•2y ago

nah I don't

Brody•2y ago

just checked, and there's nothing wrong with API calls taking up to 5s https://frantic-north-production-0ace.up.railway.app/wait/5s

rapid•2y ago

so do yk wht the issue is

Brody•2y ago

there are too many possibilities, if I were to debug id need the code

rapid•2y ago

if you'd like I can add you to the repositry

Brody•2y ago

sure

rapid•2y ago

whats ur github

Brody•2y ago

overrnet

rapid•2y ago

added, also just be prepared that its not very... "good" code

Brody•2y ago

alright ill see what i can do and get back to you, dinner is soon so be paitent please

rapid•2y ago

yeah no problem, take your time

Brody•2y ago

i have to install python first

rapid•2y ago

oh lol

Brody•2y ago

haven't done python in a while, but i used to do flask stuff all the time

rapid•2y ago

Brody•2y ago

Brody•2y ago

this is a pretty cool little api, but theres room for improvement

rapid•2y ago

for sure, like badges how's it going? have you found out anything? feel free to push a commit, its connected to the domain

Brody•2y ago

yeah, your code as is, "/picture/<id>" doesn't work, but "/<id>" does like you said, but i did some things and now it does i dont have git

rapid•2y ago

oh lol oh fr?

Brody•2y ago

yeah, let me work some things out, and then ill give you a zip file for new code

rapid•2y ago

sure also, this is asking for a lot but if you can lmk what things could be faster, it would be great

Brody•2y ago

yeah it could be written in Go lol

rapid•2y ago

oh that’s a smart idea idk go

Brody•2y ago

im only partially joking, everyone is free to use whatever langue they like

rapid•2y ago

for sure, but i’ve heard go is faster

Brody•2y ago

easier than python 😉

rapid•2y ago

sure idk i feel like python makes the most since tho yk

Brody•2y ago

but sorry i dont know too much about optimising python code, all i can do is make things "work"

rapid•2y ago

oh yeah np so what was wrong with it

Brody•2y ago

execution was hanging forever one that web request url = requests.get(f"https://presence.dark.bio/{id}")

rapid•2y ago

yea

Brody•2y ago

as i thought from the very begining

rapid•2y ago

hh huh

Brody•2y ago

but why would you want to make a loopback type request when the function that handles that request is sitting right above it

rapid•2y ago

idk I was just trying to make it work lmao

Brody•2y ago

just request the function directly okay fair lol hold on for a bit and let me get this sorted out

rapid•2y ago

ok !!!! :))))))

Brody•2y ago

try it locally

presence-main.zip

rapid•2y ago

sus download fr let me try this rq

Brody•2y ago

yeah ik, but i have no inclination to download the git cli or even use github to begin with

rapid•2y ago

yea np I was joking 😦

Brody•2y ago

alright dinner, ttyl

rapid•2y ago

ttyl its so fastomg

Brody•2y ago

Yeah it's faster when it doesn't have to make an http request to an old version of the API running on railway

rapid•2y ago

oh.. thats interesting Thanks for helping today!

Brody•2y ago

no problem, happy coding!
