TypeError: attrib() got an unexpected keyword argument 'convert'
Suggested workaround from https://stackoverflow.com/questions/58189683/typeerror-attrib-got-an-unexpected-keyword-argument-convert is to set attrs version to attrs==19.1.0 instead of attrs>=19.1.0.
Workaround is working, but better solution would be to update attrs version and use converter kward instead of convert as per this PR: python-attrs/attrs#307
