Several apps are failing with the same error message

All apps deployed successfully 1-2 days ago. They still deploy successfully locally or using Gitpod. Has something changed with Railway? Project ID: d06f7acd-76c5-48ce-bc2b-0a5e42d156b8 Error: TypeError: issubclass() arg 1 must be a class Traceback attached.

full error logs please, those look to be cut off. could you also send your requirements.txt file?

Fyi, this worked 2-3 days ago, no changes to the code since. It also works if I launch locally or in a remote env like Gitpod

the app is located in url-summary correct?

mndrOP•2y ago

Just moved the solo apps to this monorepo, but the issue persists with separate repos too Logs are from pinecone-summary deployment

Brody•2y ago

what python version are you using locally

mndrOP•2y ago

3.11

Brody•2y ago

let's try getting railway to use 3.11 to run your app create a .python-version file in pinecone-summary with the contents 3.11

mndrOP•2y ago

Testing While it builds, can watch paths be set in a template? I couldnt find that option No difference, same error

Brody•2y ago

are you sure the logs you have most recently provided are full logs?

mndrOP•2y ago

Wait, interesting, it threw the error, but deployed the app after a few seconds After I hit refresh a few times Is this an expected behavior? It's a first for me

Brody•2y ago

if I'm being honest, and I don't mean any offence, this just looks like you've written unstable code

mndrOP•2y ago

No offence taken, I'm learning.. Any quick tips?

Brody•2y ago

make sure arg 1 is a class I honestly don't know, I'm not a python dev and it's unfortunate but code questions are just a tad out of the scope of what these threads are intended for

mndrOP•2y ago

No worries. Any suggestions on the monorepo layout, or anything else Railway specific?

Brody•2y ago

nothing wrong with a mono repo you asked about watch paths https://docs.railway.app/deploy/builds#watch-paths

mndrOP•2y ago

I cannot add this to a template - would i need the .toml file?

Brody•2y ago

very good idea, let me see if you can define watch paths in a railway.json/toml file

mndrOP•2y ago

The need for .python-version was new to me, but it worked, so thanks!

Brody•2y ago

you absolutely can specify watch paths in a railway.json file

{
  "$schema": "https://railway.app/railway.schema.json",
  "build": {
    "builder": "DOCKERFILE",
    "watchPatterns": [
      "folder"
    ],
    "dockerfilePath": "Dockerfile"
  },
  "deploy": {
    "numReplicas": 1,
    "healthcheckPath": "/ok200",
    "restartPolicyType": "ON_FAILURE",
    "restartPolicyMaxRetries": 10
  }
}

{
  "$schema": "https://railway.app/railway.schema.json",
  "build": {
    "builder": "DOCKERFILE",
    "watchPatterns": [
      "folder"
    ],
    "dockerfilePath": "Dockerfile"
  },
  "deploy": {
    "numReplicas": 1,
    "healthcheckPath": "/ok200",
    "restartPolicyType": "ON_FAILURE",
    "restartPolicyMaxRetries": 10
  }
}

this uses a dockerfile, so dont use this railway.json, but you get the idea

mndrOP•2y ago

Would it be picked up for non-beta users?

Brody•2y ago

let me check, one sec

mndrOP•2y ago

Is a watch path necessary if root dirs are explicitly provided for each app in a monorepo? I add the python version file for one app, but others starting building too. Hence, I thought about watch paths

Brody•2y ago

yep if you put a railway.json file in a sub dir, and specify that dir as your root dir the railway.json from that dir does get used what is your start command for one of these python programs in the mono reapo?

mndrOP•2y ago

streamlit run streamlit_app.py

Brody•2y ago

and you are setting the appropriate root dir for each service?

mndrOP•2y ago

Yes

Brody•2y ago

odd that builds from other services build then

Brody•2y ago

you can always set your watch paths in the railway.json file

mndrOP•2y ago

I'm about to test that

Brody•2y ago

let me know how that goes

mndrOP•2y ago

{ "$schema": "https://railway.app/railway.schema.json", "build": { "builder": "NIXPACKS", "watchPatterns": [ "/pinecone-summary" ] }, "deploy": { "numReplicas": 1, "startCommand": "streamlit run streamlit_app.py", "restartPolicyType": "ON_FAILURE", "restartPolicyMaxRetries": 10 } } Does this look ok to you? Also, does json vs toml matter at all?

Brody•2y ago

you might want pinecone-summary/** its user preference, i prefer railway.json since it has a schema so that when you edit that file with vscode it will be able to tell you what you can and cant do in the railway.json file

mndrOP•2y ago

Helpful, thanks Do you have a sample .json with the root dir specified? Looking for the param to use, but can't find an example

Brody•2y ago

doesn't look like you can it makes sense to not be able to, since railway won't even know what root directory to look in for a railway.json unless you tell it first and foremost

mndrOP•2y ago

Hmm.. how should a monorepo with separate root dirs for each app be handled then?

Brody•2y ago

you set the root dir in the service settings

mndrOP•2y ago

Ok, that's how I've been doing it so far. Wanted to know if there was an IaC option, but that's fine, all good Thanks

Brody•2y ago

IaC?

mndrOP•2y ago

infra as code

Brody•2y ago

ah fancy acronym well if you have any more questions, feel free to ask 🙂

mndrOP•2y ago

I guess Railway calls it config as code 🙂

Brody•2y ago

that sounds right

Tofu Boy [COMMS OPEN]•2y ago

Hey @mndr, sorry to bother, can I dm you about this?

Brody•2y ago

are you having issues with langchain errors too?

Tofu Boy [COMMS OPEN]•2y ago

No, the weird thing is that it's a completely different project. It's just a discord bot, yet the exact same error started appearing for me.

Brody•2y ago

please open your own #✋｜help thread

mndrOP•2y ago

See if this helps -> create a .python-version file with the contents 3.11 (or whatever Python version you are using locally / where it works)
