Hi, I'm having some issues with the venv/uvicorn/fastapi backend. Everytime I run the app (

npm run start

) I get this error:

Copy code

backend/venv/lib/python3.11/site-packages/supertokens_python/utils.py:197: RuntimeWarning: Inconsistent mode detected, check if you are using the right asgi / wsgi mode
  warnings.warn(
INFO:     Started server process [57048]
INFO:     Waiting for application startup.
INFO:     Application startup complete.
INFO:     Uvicorn running on http://0.0.0.0:3001 (Press CTRL+C to quit)

The app runs fine, but now I'm wanting to do some more development on the backend, I'm having issues as I can't access Uvicorn. For example, when I try and visit the server at http://0.0.0.0:3001 I get an internal server error and it throws up a load of other errors:

Copy code

INFO:     127.0.0.1:58983 - "GET / HTTP/1.1" 500 Internal Server Error
ERROR:    Exception in ASGI application

I've been reading up about the errors and could be to do with me running this on an M1 Mac, so I've tried running Terminal in Rosetta and reinstalling everything, but it's still throwing up these errors. The full list of errors is shown in the screenshot below. Have you got any experience of these errors and what I can do to fix it? Thanks

Hey. @KShivendu can help here.

> I'm having issues as I can't access Uvicorn Why? Is this not running locally? Can you share your supertokens python setup code? Please also share how are you starting the server.

Thanks for getting back to me, no I get an internal server error every time I try to access Uvicorn.

Kranos

03/14/2023, 11:01 AM

I am starting the server using npm run start in the parent folder that has both the frontend and backend folders in it

Kranos

03/14/2023, 11:02 AM

This then runs the following in the backend folder:

pip install virtualenv && virtualenv venv && chmod +x venv/bin/activate && . venv/bin/activate && pip install -r requirements.txt && python app.py

Kranos

03/14/2023, 11:04 AM

This then results in the following:

Kranos

03/14/2023, 11:06 AM

So, Uvicorn does get up and running on

http://0.0.0.0:3001

as expected. However when you try to access it, it will throw an

Internal Server Error

and produce the following in the Terminal:

I haven't changed the supertokens python set up code and have these two files in the backend folder: app.py and config.py

Kranos

app.py is as follows:

Copy code

Hi @KShivendu - did you get a chance to look at this at all? I've done some more testing and I can't work out how my app is even working with this error - I can't even ping

http://localhost:3001

without creating an

Internal Server Error

so I'm not sure how my app is calling

/sessioninfo

correctly and not crashing

rp_st

03/14/2023, 3:54 PM

hey @Kranos - @KShivendu will reply as soon as he is available

Kranos

03/14/2023, 3:54 PM

Thank you!

KShivendu

03/14/2023, 5:54 PM

Hey @Kranos, I was able to replicate the issue on my machine. So basically it's happening because of (breaking) changes in

asyncio

of python3.11. I noticed that some other OSS projects have also reported this issue https://github.com/home-assistant/core/issues/88990 The simplest solution is to simply downgrade to python 3.10 which is more stable. If you're using Debian based os, you can do:

Copy code

sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt install python3.10

I hope it helps. Let me know if you need help with anything else 😄

Kranos

03/14/2023, 5:54 PM

Amazing, thank you - will give it a try!

Kranos

03/14/2023, 10:47 PM

Hi, I managed to downgrade to 3.10.10 but now when I run the app, it crashes out with the following: I think this is because I'm running an M1 mac?

Indeed this is happening because of M1. Many other OSS projects have reported this issue with

cryptography

and

pycryptodome

library. You can look into them to find what exactly works for you.

KShivendu

03/15/2023, 1:21 PM

pip install cryptography pycryptodome --no-cache-dir --verbose --force-reinstall

seems to have worked for many people.

Unfortunately, I don't have M1 so I cannot replicate it. Let me know if it's still hard to fix this one or if you face some other issue 😄

03/15/2023, 2:13 PM

Argh.... still can't get it working I've downgraded to the following:

yeaa.. this is not even from our sdk anymore - it's from openAI's SDKs

I don't think it is, I've just got my project saved in a folder I've called OpenAI...

The issues seem to be in the venv module of Python

Yea I had faced this issue too when moving to m1 Mac.

I had to update my python to the latest one and run a bunch of commands for it to work. Stack over flow helped mostly

I don’t recall what it was. But it was reallly annoying

Kranos

Yeah, going through the same thing! Been on Stackoverflow, GitHub etc looking for solutions and still haven't found the right one yet. Been a couple of days now, hopefully I'll get there!

Good luck 🙂

I haven't been able to resolve these errors so have decided to run the backend as a Docker container, which seems to be working now and probably a better way to set up in the long run anyway. Thanks for your help though!

Cool. You can setup VS code dev containers as well.
