This build offers a "Replay" link sending POST to https://ci.jenkins.io/blue/rest/organizations/jenkins/pipelines/Core/pipelines/jenkins/branches/PR-2905/runs/3/replay/

The response is HTTP 500, message "Run was not added to queue.", and an empty errors array. Nothing is shown on the UI, the message is only in the HTTP response. It's like I didn't click anything.

Meanwhile, the classic UI at https://ci.jenkins.io/job/Core/job/jenkins/job/PR-2905/3/ does not have a 'Replay' link, presumably because the Pipeline failed so early.

• Terrible UX of not getting any visible response after clicking.
• Don't offer an action that's not available in the first place, or explicitly say it can't work when clicking.
