django-rest-framework: UnsupportedMediaType crashes post_exception_handler

[KPilnacek]

Hello,

we are happy users of rollbar but recently we came across the following problem:
When we use the following settings:

REST_FRAMEWORK = {
    'EXCEPTION_HANDLER': 'rollbar.contrib.django_rest_framework.post_exception_handler'
}

and UnsupportedMediaType error is raised, the request fails with 500 status instead of 415.

The problem is in the line 21

context['request']._request.POST = context['request'].data

where the data attribute tries to read the data but these cannot be parsed as the media type is not supported.

For now, we created the following workaround:

from rest_framework.exceptions import APIException, UnsupportedMediaType, ParseError
from rollbar.contrib.django_rest_framework import post_exception_handler, RestFrameworkExceptionHandler

def custom_exception_handler(exc: Union[Exception, APIException], context: dict) -> Response:
    # Call Rollbar's post exception handler first, to get the standard error response.
    try:
        return post_exception_handler(exc, context)
    except (UnsupportedMediaType, ParseError):
        return RestFrameworkExceptionHandler(exc, context)

But is there a proper way how to handle this?
With regards
Krystof

This will need to be addressed in the upcoming release. Thanks for sharing your temporary solution for now :)

It looks like this was never fixed as promised, but I fixed it with PR #335
