sadly an error occured when I tried to trigger a build :(

Looks like the bot hasn't been able to automatically start lite builds on collaborator submitted pull requests lately, e.g. nodejs/node#25516 (comment), and reports:

Thanks for reporting! This might be related to some recent changes that got deployed last week. I'll double check the error logs for details later today.

Found one error related to that PR:

There's lots of other successful Jenkins -> GitHub updates before and after the above, so I'm assuming it's related to the PR somehow.

Much appreciated! Grepping through logs from previous days, I also started realising this wasn't a unique error.. What's common between the ones I've seen, is they're related to webhook events from opened PRs.

Maybe related to #209? 🤷‍♂️

Similar errors from other days;

Alrighty, #209 is now live in production. I'll remember to double check for these errors logs the next day.

[phillipj]

This looks promising:

19:42:45.235  INFO bot: Jenkins build started (req_id=58a89c50-18f5-11e9-a5d5-f9690fa1f072, pr=nodejs/node/#25523, action=pull_request.opened)
    buildUrl: https://ci.nodejs.org/blue/organizations/jenkins/node-test-pull-request-lite-pipeline/detail/node-test-pull-request-lite-pipeline/2257/pipeline

Closing this issue for now, feel free to re-open if I'm wrong :)
