ValidationException returns stack trace instead of a list of violations

[mtret]

API Platform version(s) affected: v3.2.16

Description
Hi, anyone knows why this is happening in 3.2.16? Basically throwing ValidationException used to return nicely formatted violations list, now it returns html and stack trace for some reason. Thought maybe setting rfc_7807_compliant_errors: false
could fix it, but it seems to have no effect. Is it supposed to behave like this? If so, any possible workarounds?

How to reproduce
Throw a ValidationException in a custom controller.

Possible Solution
No idea.
