Not working for multiple workers by uvicorn

[maveius]

Describe the bug Did anyone tried to use it for multiple workers >1 like 4 ? uvicorn app.main:app --host 0.0.0.0 --port 8001 --workers 4 When multiple workers by uvicorn I think that different sub-processes are inside and session is not shared between workers (processes) then issue like detail "AADSTS501481: The Code_Verifier does not match the code_challenge supplied in the authorization request. Trace ID:..."

To Reproduce Steps to reproduce the behavior:

1. Run in docker by uvicorn app with workers 4 uvicorn app.main:app --host 0.0.0.0 --port 8001 --workers 4
2. Click on login button
3. Wait for result
4. See error "AADSTS501481: The Code_Verifier does not match the code_challenge supplied in the authorization request. Trace ID:..."

Expected behavior It should not depend on which worker has this code in memory in one single session, but should share between processes.
