Hi @mphilbrick211 could you have a look at why my cla check is failing here? I don't think anything has changed since this check succeeded last week? #287

[sarina]

@pomegranited it doesn't look like the check is failing, it's just stalled, which I don't have a way to kick. Can you push an empty commit?

[pomegranited]

@sarina Tried re-pushing, but same effect.. and I'm not sure where that check is triggered from (it must be in the repo settings, not the .github/workflows?)

Commenting should rerun the cla check.

@e0d huh, that's weird... because Jill & I did comment to no avail. Anyway thanks for the magic comment 🪄 !

I don't think my comment worked 😞 I think there's something weirdly stuck here. I'd try a new branch and PR.

Closed in favour of #291
