GraphQL error: Field 'troubleshootJobWithAi' doesn't exist on type 'Pipeline'

Look at this pipeline <https://gitlab.common-lisp.net/cmucl/cmucl/-/merge_requests/265/pipelines>. Part way down, there appears an expand button with the label "Failed jobs". This seems new. Anyway, I clicked the button and I get the GraphQL error in the subject line. I guess this new thing (?) isn't working quite right. But I probably don't need AI to tell me what I screwed up in the CI job. :-) At least in this pipeline. ​
