Hi @jywarren....I believe this should work for our purpose. Fingers crossed that it actually does 🤞

[jywarren]

OK, maybe there was still an error? I see https://github.com/publiclab/mapknitter/pull/1740 which was created just after we merged this!

[jywarren]

Error: TypeError: Cannot read property 'number' of undefined
Error: Cannot read property 'number' of undefined

Same error with "number" as i documented... i hope the action author writes back!!

[PeculiarE]

it is working actually, see this PR #1741 opened roughly 10mins after the merge. The comment is made as desired.

I dunno if you saw my comment over at #1734, but I did mention that I decided to no longer use that author's bot. I went ahead to create our own specialized workflow to make the comment using the Github API and Github Actions. Full details here.

I believe the merge had not yet fully completed before #1740 was opened. Because I'm looking at the workflow/checks in its thread now and it's running the old workflow that uses that author's bot (Label Actions / Process Label Action) and that's why it threw the 'number' error.

The next PR opened at #1741 contains the new workflow I created: 'Dependabot PR Auto-Comment task' and this workflow does the job 😄

Oh fantastic!!! You must be right. Yes possibly the rebase was only up to a certain commit or something?

Great work, thanks @PeculiarE !!!
