Hi @rishabhpoddar @namsnath I have made some changes to support litestar but the tests are failing need some help here since I couldn't debug where the issue is exactly coming from can any one guide me through what am I doing wrong?

📝 Documentation updates detected!

New suggestion: Add Litestar framework support documentation

Hey @pythonhubdev ,
Thanks for the contribution!

Which test suite has the failures? Any specific tests?

I can take a look at this in detail sometime next week.

Hi @namsnath thanks for the response so except the top tests all other tests are failing. Mainly the tests that are calling the internal API of supertokens are failing but they are passing in FastAPI I don't know if I have to mount / attach the app or something so mostly it's 404 a little guidance help me I can fix it and the other issues are 500 Internal Server Error I don't know exactly why it's failing.

Hi @namsnath I have updated the test and modified the Litestar middleware to use ASGIMiddleware as well but the routes related to supertoken i.e all the routes following /auth are NOT FOUND. Can you help me in fixing this even if you guide me where I have to look into I can take it from there. Thanks

Hey @pythonhubdev ,

I see that you're using the domain as testserver.local. This is probably the cause of the 404s you're seeing in tests.
This is probably not the issue. I will look into this and get back.

When you fix this, please also make sure the code works in the lowest supported version of Python (3.8). You seem to be running Python 3.10+.

I'll add a few more review comments later today and look at the framework in detail sometime later.

Hi @namsnath the major issue is I was not able to access those routes even manually not alone in testing I think the app is not getting attached or something is getting missed out due to some reason I can't access the /auth/dasboard route even. Can you guide me a little more please?

@pythonhubdev ,
I looked into this and found a few interesting issues.

• The requests to SuperTokens routes are not defined in the route_handlers, and result in a 404.
• Litestar handles 404/405s at the app level, and thus these do not flow down to the middleware and are handled directly through the exception_handlers map.
• exception_handlers can not be async functions, so it does not seem possible to call the ST middleware through these and handle the request.

I could get the requests routed correctly with these changes in the example app:

# supertokens_python/framework/litestar/litestar_request.py
class LitestarRequest(BaseRequest):
    ....
    def get_path(self) -> str:
        return self.request.scope["raw_path"].decode("utf-8")

# main.py

# TODO: Move to `litestar_middleware.py`
# If using the import from `litestar_middleware` does not work, convert to a factory function
@asgi("/auth", is_mount=True, copy_scope=True)
async def supertokens_app(scope: Scope, receive: Receive, send: Send) -> None:
    # <code from `LitestarMiddleware.handle` without `next_app` handling>
    # Additional changes:
    asgi_response = result.response.to_asgi_response(app=None, request=request) # Removed `await`, Set `app=None`

app = Litestar(
    route_handlers=[supertokens_app, ...],
    # middleware=[],
    exception_handlers={...},
)

A few things to keep in mind for this PR:

• Code needs to work on Python 3.8
• Please set up hooks by running make set-up-hooks
• Try to make sure types are correctly mentioned, and avoid Any wherever possible

I'll add a few items to the TODO section of the PR as well.

@namsnath fixed the PR comments working on the ASGI handled you mentioned some are failing and facing some issues too will fix and update.

Hey any progress on this ? Does this need to be picked up ?

Hi, I may require some help in this facing various issues and things are failing
