unknown error from gunicorn thrown (in logfile) if authlib is used: "ValueError: count must be a positive integer (got 0)"

the issue is only visible to me in the logfile - unclear if there are more impacts => there is no logging available where I can see more - I even activated DEBUG level and nothing is being added

How to reproduce the bug

pull latest images from dockerhub docker pull apache/superset:1.5.1 start container add authlib (pip install authlib - for me its 1.0.1) add configuration for oauth initialize container start container login

Expected results

no error visible

Actual results

@skyonedot for now add this to your dockerfile after you have installed superset.

RUN pip install --force-reinstall git+https://github.com/benoitc/gunicorn.git@master

[skyonedot]
