RFR: pr: handle exceptions when fetching commit comments

[Erik Helin]

Hi all,

please review this patch that handles exceptions thrown fetching commit comments for a repository. Handling here means logging the exception and moving on, there isn't much more we can at this point in the code.

Thanks,
Erik
