Subject: [PATCH] fix: Let's be more specific about "not implemented" (#31237)

Summary:
After installed a third party library I just got "Error: not implemented" without any other informations in the stack trace. Adding a more specific sentence within the error's message can be useful to understand what is going on.

## Changelog

[General] [CHANGED] - Added context to URL's error messages when the feature is not implemented
