When you return a response object, pyramid bypasses the renderer. In your
case, you would need something like::
import json
@view_config(route_name='route', renderer='json', request_method='GET')
def view(request):
error = {'message': 'Could not process entity'}
return HTTPUnprocessableEntity(
body=json.dumps(error),
content_type='application/json')
