It seems the jenkins job for this repo got accidentally removed (while the zuul trigger is still there) in 2013 from integration/config https://gerrit.wikimedia.org/r/84869 84b0bda03fa64990af43f1771f97b1133e377a65 Iad334b832d889ca50a16e82ad4c6124b4b3f01f1 (can't access this via gerrit, but it is in the repo). The jobs is still there in our Jenkins https://integration.wikimedia.org/ci/job/analytics-wikistats/ , but it might not work anymore.
Yup that is related to T97514: Migrate "analytics-*" jobs to Jenkins Job Builder. From there, I think I removed the jobs from JJB because analytics at the time wanted to configure them via the webUI.
Maybe merge this wikistats task in T97514?
