Deploying issue: Python Flask server

Hi, first off thank you for helping, I have been trying to sort this most of the day 😄 I have a Flask server written in python that is running fine locally in VSCode, but when I try to run it with railway it is failing. The deploy logs are showing:

Traceback (most recent call last):

File "main.py", line 2, in <module>

from logic.reqs import getArtists, getArtistInfo, updateCookie

File "/app/logic/reqs.py", line 12, in <module>

def fetchCookie() -> str | bool:

TypeError: unsupported operand type(s) for |: 'type' and 'type'

Traceback (most recent call last):

But I am completely unsure why or where the issue is based on this. Any help at all would be the best for me thank you again

Solution:

set your start command to gunicorn main:app

what version of python are you using locally

BeepOP•10mo ago

Hi! 3.10.6 in VScode

Brody•10mo ago

what version is railway using

BeepOP•10mo ago

Where can I see that sorry? I just removed all my return type annotation -> bool ect and its running now 🤔 maybe that was it! But when I make a request the public url on railway im getting 301 so maybe its still broken

Brody•10mo ago

at the top of the build logs

BeepOP•10mo ago

Ah yes, python 3.8

Brody•10mo ago

add a runtime.txt to your project with 3.10 in it

BeepOP•10mo ago

Okay yep now its on 3.10 But still getting 301 when I try to access the server 🤔

Brody•10mo ago

that's a redirect, are you sure you are using https

BeepOP•10mo ago

My bad sorry! I now get 503 with https://

Brody•10mo ago

what's your current start command

BeepOP•10mo ago

For my python code?

Brody•10mo ago

the start command in use by railway

BeepOP•10mo ago

I havent set one so I think its just using main.py

Brody•10mo ago

please check

Okay I set it to "python main.py" The deloy logs have

* Serving Flask app 'main'

* Debug mode: on

But still 503 for /cookies for example as well as all end points on my Flask server 🤔

Brody•10mo ago

Is that better than flask? Happy to swap 🤣

Brody•10mo ago

fixed, but make sure you have gunicorn in your requirements.txt

BeepOP•10mo ago
