Summary

Using v3.9 of python and suddenly starting to get this error.

I have no idea why its falling over as the logs on Vercel isn't giving me enough information to try fix it.

It runs locally fine and recently moved to pipenv as seems that might be better for vercel python function.

Any ideas would be greated appreciated.

Example
