How to reproduce
Use Error::createFromException with a ValidationException.
https://github.com/ecamp/ecamp3/blob/renovate/api-platform/api/src/State/ValidationErrorProvider.php#L37
PR: ecamp/ecamp3#9231

Possible Solution
A check must be put there + a fallback to the previous path where $exception->getMessage() is used for the detail.

Additional Context

[soyuka]

Mhh you're probably doing something unconventional as createFromException shouldn't be called from a default validation error. This still deserve fixing.

Is fixed with 4.3.1, thank you.
