Mapper_parser_exception get column error

Elastic Stack Elasticsearch
1

Is it possible to get the name of a field which is getting the error mapper_parser_exception?
I have an script in python and I get the following error:
TransportError(400, u'mapper_parsing_exception', u'failed to parse [ID45]')

But I am not able to catch the field's name "ID45" in a easy and clear way.

Thanks
