Hello - I've been using pulumi v3.75 with python that's been working for a while now. But suddenly it's now throwing this error:

Any advice as to why it suddenly broke?

Hey Seth, sorry you hit this error. This looks like a bug on our side. It'd be amazing if you could raise an issue with reproduction steps so we can fix it!

Thanks for that Seth! Could you also include some information on how to reproduce the error? Do you know what in your pulumi program causes the issue? It'd help us a ton if we can reproduce the problem.

Unfortunately I don't know exactly where in the code it's breaking. I actually just tried to do "pulumi about" with pulumi v3.75 and it gets on the same error with pulumi about which I assume is not related to the python program? The python program was also working about 1-2 weeks ago, but suddenly broke.
We haven't made changes to the python program in a couple months.

I see, I'm sorry to hear that. Could I ask you to add some verbose logs so we get an idea of what's going on? I think
pulumi about
crashing is particularly unexpected. There's instructions on how to enable that here https://www.pulumi.com/docs/support/troubleshooting/#verbose-logging
