How to raise validation exception for DurationField to GUI

[Looping Ydobon]

Hello,

DurationField does not cover cases when input value cannot be converted to timestamp :

timedelta(1000000000) # OverflowError: days=1000000000; must have magnitude <= 999999999
timedelta(100000000000) # OverflowError: Python int too large to convert to C int

Therefore I made a custom/inherited DuurationField class to cover those cases and tried to raise a ValidationError inside to_internal_value().
However, only err 500 is visible on GUI side :(

Can someone give a hint on where this error is to be handled?

You don't raise exceptions at serializer.

serializer.is_valid(raise_exception=Flase)

now everything works fine - turned the Validation error raise to self.fail() call
