glasgow: running Glasgow exectutable produces "TypeError: expected string or bytes-like object" in packaging\utils.py

The example below is a build command but even just running Glasgow without any arguments, produces the same error. I updated to commit 62e27d9941bf22d1fdb73681af7eb74e96be775a. This is still on python 3.9.

I did try forcing it to be string in plugin.py: if requirement.marker and requirement.marker.evaluate({"extra": str(dependency)}):

but after doing so I get an issue with the aiohttp dependency (so I don’t know if this was the right thing to do):

    import aiohttp, aiohttp.web
ModuleNotFoundError: No module named 'aiohttp' 

Here is the full trace:
