Custom error message for missing field

[Tomtouta]

Hello,

I discover recently the way to customize error message using this feature : #440

Nevertheless, I don't find a way to define error message in case of missing field in a json message
For example, if a json schema expect to have an id but the json sent by a user does not contain this id, I want to have a specific error message saying something like "JSON schema not respected, missing id field".
How can this be done ?

Regards,

Tom
