get_restriction_fragments tag fails on AWS

[edmundmiller]

Description of the bug

'^GATC' is not a valid value for TagValue - it contains illegal characters (Service: AWSBatch; Status Code: 400; Error Code: BadRequestException; Request ID: fcf9910c-c9f6-46fc-bca4-8aa1258226b5; Proxy: null)

The issue is based on the tagdefinition in this module.

Work around for now is adding:

 withName:GET_RESTRICTION_FRAGMENTS {
      tag = ''
   }
