Comment 8 for bug 1982227

That fix can be backported as long as it does not break the previous versions.
The serious problem this is revealing is that we are pulling dependencies which have never been tested with wallaby (and WILL never be tested as we won't bump u-c in stable branches)

There is one more fix which looks like a fix for sqlalchemy 1.4 I can find from git log and there might be a few more.
