Should JSON BodyParser return 400 if JSON parsing causes an exception?

When I am parsing custom classes with the default JSON BodyParser, if an exception is thrown during parsing - e.g. if my class has a require() condition which wasn’t met - a 500 is returned for the request. I think this scenario should return a 400 Bad Request - if attempting to parse the input to my custom type threw.

How can I extend the json BodyParser or create my own to achieve this?

Hi @mrubin
Well I dont think this is reponsability of Json Body parser. This should be handle in Using that you can customize any exception before reaches the client. Than you can create an 400 exception with Json Body Parser error as cause.

example: BadRequestBodyException(message=“Wrong Body”, cause=JsonError)
something like that
