Seems one of our recent Vite integration merge requests broke instanbul, a tool that we use to collect coverage because we added import.meta calls:

https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/assets/javascripts/entrypoints/main.js or https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/assets/javascripts/entrypoints/main_ee.js

Here is the failed job log https://gitlab.com/gitlab-org/gitlab/-/jobs/5596785620#L4544

which has the following error:

Failed to collect coverage from /builds/gitlab-org/gitlab/app/assets/javascripts/entrypoints/main.js
ERROR: Cannot assign to read only property 'message' of object 'SyntaxError: import.meta may appear only with 'sourceType: "module"' (63:26)
