### What you expected to see, versus what you actually saw

That Dependabot can generate a PR.

This is a private repository, I can share the information with GitHub Support if they want.

I have a local `.whl` file that is in my source code that is used in my dependencies (it's a third party wheel that I need to use).

Instead, I see in the logs:
