Feature Request: Ignore Fail

[AsheKR]

If there is no additional commit, there will be an error, so I would like to add a function that can skip this error.
if you have any ideas or corrections, please leave a comment

For me it also happened that i received an error because there haven't been commits between upstream and my fork. Usually this error should be handled here:

https://github.com/TG908/fork-sync/blob/e15fc5e857fee00f9ba8b239fc3546e4612ed0c6/src/main.ts#L20-L22

but in my case the error message was something like

No commits between master and master

so the check didn't succeed because it expects a error message like 'No commits between ' + context.repo.owner + ':' + base + ' and ' + owner + ':' + head.

But what i also noticed is the http error code 422 saying "Unprocessable Entity". So it might be an option to edit the mentioned line of code like so:

if (!!error.errors && error.status == 422 && error.errors[0].message.startsWith('No commits between')) {
      console.log('No commits between ' + context.repo.owner + ':' + base + ' and ' + owner + ':' + head);
    }

This would be a bit more robust i think.

Good catch. Thank you!

@R0Wi
I think it's a different issue from that one.
I think it would be good to open and apply a new issue. 👍

[R0Wi]

Agree on that. I'll open a new issue with a PR attached :-)
