Error in logger.error() call: 'list' object has no attribute '_code'

Traceback (most recent call last):

It seems that soap_error is a list.

EDIT: The soap MESSAGE is:

b'<?xml version=\'1.0\' encoding=\'UTF-8\'?><S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/"><S:Body><createResponse xmlns="http://www.docdatapayments.com/services/paymentservice/1_3/" ddpXsdVersion="1.3.14"><createErrors><error code="SECURITY_ERROR">Login failed.</error></createErrors></createResponse></S:Body></S:Envelope>'

A pull request would be welcome to fix this (this is probably changed in the 1.3 XSD)
