I believe this has to do with the docker CI not actually being in prod env as the footer version only actually shows up on prod environments and not dev. Might be the cause of other Docker flakes as well as I believe E2E tests were built with the prod env in mind.

Yup, I have checked it yesterday. Currently there are issues with dev-server starting in prod environment, once do will commit changes. Thanks @jnvtnguyen for looking.
