Could also be backend validation is broken, so FE just shows the user something useful rather than waiting for backend to reject and show a generic error message.
I mean… I've been both. I have had to punt a problem that caused FE anguish because the project is old, not the priority, and hard to make changes to.
I've also been the FE that was told that they are aware of the problem, and can't get to it for a month, so we need to at least make the UI surface the error in a better way so that the user can go to support for manual intervention.
Huh? If backend has incorrect validation on the old password string, and returns an error message like "invalid password" without specifying if it's the old or new password, that's not particularly helpful for front end. And that's pretty common for an API response not to have fine grain details.
The UI is capable of validating up front before the service request, assuming they know the exact validation rules BE uses.

Found the FE dev. I think there is a JavaScript library for finding ways to blame the backend.

That would be actively malicious. I don’t know how anyone could get the idea to just show “something” if the backend sends a generic error message.

Or the FE just fucked up. Both are plausible.
