Comment 0 for bug 1815657

There are 2 unit tests failing with python 3.7. This can be recreated on Ubuntu Disco by running the py35 target which by default will use python3 which is /usr/bin/python3 which is python3.7 in Disco. python3.7 is also available in bionic so you can likely update tox.ini to specifically use python3.7.

Failed 2 tests - output below:
