I don;t think this is a charm issue. It looks like an incompatibility between ceph-isci and python3-werkzeug in groovy.

Could you also confirm if this is happening only in Groovy? I see the following versions of those two packages in case this is really an incompatibility issue:

If Liam's assumption is correct it should not be working on Hirsute as well, and it might be working on Focal since there we have an older version of python3-werkzeug.

I have tested focal and groovy and is only happening on groovy. I have not tried Hirsute.
