This seems related to this issue:

• incompatible with werkzeug 2.2.0, can't import parse_rule maxcountryman/flask-login#686

After pinning the werkzeug version to 2.1 in 1bf40ce, the problem was fixed, and I was able to deploy this branch on beta.simoc.space.

[ezio-melotti]

Upstream flask-login issue seems to be fixed, so I unpinned werkzeug version and redeployed on beta, and everything seems to run smoothly now.
We still need to test on GCP before merging.
