This is correct.

I'm using tg1 and you can just add the following into your set of
jsonification rules, conventionally in json.py:
@jsonify.when('isinstance(obj, Invalid)')
def jsonify_tg_errors(obj):
result = { }
result['msg'] = obj.msg
result['value'] = str(obj.value)
error_list = getattr( obj, 'error_list', None )
error_dict = getattr( obj, 'error_dict', None )
if error_list is not None:
result['error_list'] = str(error_list)
if error_dict is not None:
result['error_dict'] = str(error_dict)
return result
I bet it's not perfect but works for me pretty well. I don't know
about tg2 though.
HTH,
Daniel
