pgadmin4 fails to start after upgrade

I have been running pgadmin for in a virtual environment. Today I upgraded
to v 4.6.7. Now, starting pgadmin4 throws and exception

I've tried updating to all the latest versions of things in the virtualenv
-- incuding jinja2. results of the pip install pgadmin4 --force-reinstall
were

So it seems everything is at the correct levels. Is there a bug in the
current pgadmin4 code?
