[Python] How can I access the /docs or custom routes end point while using fastapi as backend...

I am using supertokens to build an authentication system and using fastApi as backend but while using their prebuild UI and already setup backend code in python, I am not able to access the 127.0.0.0:3000/docs endpoint. It is showing only a blank page. Also, the custom routes that I have built in my API are not working and accessible.

Here is the code that I have written


@app.get("/sessioninfo")
async def secure_api(s: SessionContainer = Depends(verify_session())):
return {
"sessionHandle": s.get_handle(),
"userId": s.get_user_id(),
"accessTokenPayload": s.get_access_token_payload(),
}


Here is the app_info part of init function in supertokens

app_info = InputAppInfo(
app_name="demoApp",
api_domain="http://localhost:3001",
website_domain="http://localhost:3000",
)


After hitting the API with port 3000 and endpoint /sessioninfo I am getting blankpage localhost:3000/session_info

And for localhost:3001/session_info I am getting an internal server error. localhost:3001/session_info
