AddSource option break log w/ relative module

If I use a relative module (go mod edit -replace some/lib=/home/user1/some_golib) while the AddSource option is set to true, then no logs are emitted.

I suspect the Handler to return some error while attempting to fetch to root directory (or other). AFAIK Handler method return value is never checked (a part from tests). The failed to acquire log part should instead maybe be skipped, instead of skipping the full log message ? The error would still be returned
