This error certainly looks a bit confusing. The root of the error is that <> contains a tab at the end of the tile, which has then been propagated to the commit message that will be used for the final commit. Normally you’d see what this commit message looks like, but it won’t be shown until the check passes..

We should ensure that the the check filters tab characters from issue titles I think, I’ll file a bug for this.

Meanwhile, I edited the propagated title in your PR to unblock it, hope you don’t mind.

Best regards,
