Summary
Jinja is a dependency of Flask. In Jinga 3.1.0,
escape
is deprecated and should be imported from MarkupSafe. We can pinjinja<3.1.0
to work around this for now.Probably the better fix will be to update Flask, but since we are already pinning it to an older version it seems likely that we can't do this easily.
