Hi @wkitlasten. Thanks for raising this issue, I missed this one here: #2408.

It seems like typecasting exe_name to string can fix it, but I'll double-check and try to add possible missing tests.

Which python version are you using?

[wkitlasten]

Thanks. I am using: Python 3.12.9

@wkitlasten this should be fixed by #2457 but please reopen if not
