AFFECTSRootCause

The parameter to `Depends()` can be any Python callable — so long as `verify_token("red")` returns a callable with the right syntax and type annotations. Tension: FastAPI can use it as a dependency. Outcome: The easy way is to have the function return another function.

AFFECTSRootCause

To resolve the above issue, I added the below redirect URL to the Web Platform in the Api App registration. — cross-origin authorization code redemption. Outcome: After adding the redirect URL, I ran the application.

AFFECTSRootCause

added `datetime.now()` to get start and end time but it will execute only once — code where I have added `datetime.now()`. Tension: your code is executed only once when the application started. Outcome: I have added scheduler code in lifespan.

AFFECTSRootCause

`DB_ASYNC_TEST_CONNECTION_STR="postgresql://postgres:pass/db_tests" ` — In the `.env` file. Outcome: Changing it to `postgresql+asyncpg://` solved the error.

AFFECTSRootCause

calling self.session_factory() returns a method object instead of a context manager

REQUIRESSolution

If you convert all operations to perform asynchronously (using `aiosqlite`) , the issue will be mitigated. — When a route in FastAPI is listed as asynchronous (`async def`). Tension: that doesn't fully solve the inherent single writer problem of Sqlite. Outcome: Here's a fully operational update of the FastAPI server logic:.
