wait-for-build throws error on PR page

[janpio]

(Firefox 68.0.2 (64-bit) on Windows 10, plugin version 19.9.2)

Happens for me on for example this PR: fastlane/fastlane#15255

I don't know if this actually breaks anything, but I guess it should be fixed anyway.

Same on Chrome:

I cannot confirm this. Is there any other extension interfering?

[janpio]

No, I tested with only Refined Github enabled.

I can only reproduce on repos where I am admin or can merge PRs (feature probably only runs there).

Any way I can help debugging this?

[janpio]

This seems to be the code failing here:
https://github.com/sindresorhus/refined-github/blob/be74449658e54b01397eca2766d8aab3ac0a54ce/source/libs/pr-ci-status.ts#L7-L9

This is the full HTML code of the page as it is shown to me:
https://pastebin.com/Ry8HbgF2

This is the only occurence of commit-id:

  <div class="text-right">
    <code>
      <a href="/fastlane/fastlane/pull/15255/commits/e27e62e21686e4a9ae2962a8d0589c9f41aaf26b" class="commit-id">e27e62e</a>
    </code>
  </div>

commits-pushed does not appear at all, but if I understand the code snippet correctly that is exactly what should not appear for a match, correct?

[jerone]

I can only reproduce on repos where I am admin or can merge PRs (feature probably only runs there).

I still can't confirm this error. For example jerone/PackageSize#2, this is an PR and I'm admin of this repo. Checkbox is visible and no errors in console.

commits-pushed does not appear at all, but if I understand the code snippet correctly that is exactly what should not appear for a match, correct?

I'm not familiar with this feature, so I'll let @fregante answer your questions.

What do you get in the console when you execute the following snippet $$('[id^="commits-pushed"] .commit-id');?

[janpio]

New unclosed PR where I get this error:
fastlane/fastlane#15269

What do you get in the console when you execute the following snippet $$('[id^="commits-pushed"] .commit-id');?

22:54:17.015 $$('[id^="commits-pushed"] .commit-id');
22:54:17.026 Array []

[jerone]

Ah yes, I can confirm. It needs to be an unclosed PR.

That selector probably needs to be changed to select.last('.js-commit-group-commits .commit-id').
