Mirroring Emailed Error Message Does Not Identify Where It Is Coming From

Summary

I received this error message email and it does not tell which project generated the error. It only links to the remote mirror project.

I set this up ages ago and have no recall where I might have mirrored that repository

Steps to reproduce

1. Setup a repository for mirroring
2. Cause the refs to diverge
3. Receive the error
4. Attempt, from the error alone, to tell what project the error was generated from.

Example Project

What is the current bug behavior?

See above.

What is the expected correct behavior?

That the project where the mirror is defined is identified so the problem can be corrected.
