After Updating to Jenkins 2.250 Release Promotion stopped working with a HTTP 403 No valid crumb error.
When I click "Promote build" the following error page is shown:
HTTP ERROR 403
No valid crumb was included in the requestURI:/jenkins/job/crm/job/pdfforms/102/promote/submit
MESSAGE:No valid crumb was included in the request
The page now shows a spinner that keeps "loading":
When opening the Promote build page:
The network log shows a failed request (HTTP 403) to jenkins/$stapler/bound/24d5f473-29b8-4374-8198-9554db4ecc60/loadBuild
the jenkins logs contain a corresponding message:
2020-08-10 08:30:07.470+0000 [id=86246] WARNING hudson.security.csrf.CrumbFilter#doFilter: No valid crumb was included in request for /jenkins/$stapler/bound/24d5f473-29b8-4374-8198-9554db4ecc60/loadBuild by username. Returning 403.
When I press the "Promote build" button a corresponding warning is logged to the jenkins log:
2020-08-10 08:28:44.751+0000 [id=84705] WARNING hudson.security.csrf.CrumbFilter#doFilter: No valid crumb was included in request for /jenkins/job/crm/job/pdfforms/102/promote/submit by username. Returning 403.
