Can't find source repository if the fork has a different name than the repo

The issue seems to be that the fork where the PR was made from has a different name than the repo where the bot resides on.

@athei is there any reason why people need to have the forks named differently?
if it common use-case or rather rare exception?

Thanks!

No, I don't think that is a common scenario, but supporting forks in general def is.
