Hi, We've had a few release job failures in Kayobe [1]. I created some new tags on stable branches last week, and the release jobs failed with the following: Unable to freeze job graph: Unable to modify final job <Job trigger-readthedocs-webhook branches: None source: opendev/base-jobs/zuul.yaml at master#112> attribute variables={'rtd_webhook_id': '74820', 'rtd_project_name': 'kayobe-release-notes'} with variant <Job trigger-readthedocs-webhook branches: None source: openstack/kayobe/zuul.d/project.yaml at master#2> It's not clear from the email which branch, tag or job this affects. The message above references our readthedocs job which aims to publish release notes, although I can't see the expected releases on tarballs.o.o or PyPI. The RTD release note Zuul job is defined here [2], is it causing a problem? We also use the docs-on-readthedocs template to update our docs.
