To fix this we had to create a free trial account on cypress and enable the recording of the test. That way we found out the issue was with a locale: ![image (38)](https://github.com/user-attachments/assets/db2fad23-6fec-47c0-8c6f-a93f3e4e4c4c) Probably, this works well locally because our local machines do have a default locale, but probably we don't have one when running in CI, and millify library is causing the tests to fail specifically at this line: 363911c4a1/frontend/src/component/common/AvatarGroup/AvatarGroup.tsx (L89) (validated [here](https://github.com/Unleash/unleash/pull/8040/files#diff-afc857890da2221bd34feed0ff45dd7745ff32fb0b27055214cbe69896d5311dL89)). Unfortunately, upgrading millify didn't help, but downgrading to v5 (which doesn't support locales), solve the issue at the cost of not having the up-to-date library: https://github.com/Unleash/unleash/pull/8048 I believe the issue is related to this locale `c` reported here: https://github.com/cypress-io/cypress/issues/7890#issuecomment-2105991364 because only after overriding the languages this worked
