Migration Plugin

here's my migration plan:

{
   "plugins":[
      {
         "type":"docker",
         "repositories":[
            {
               "name":"9084e06f-8a31-46ed-b762-eb2c63c646c4",
               "repository_versions":[
                  {
                     "pulp2_repository_id":"9084e06f-8a31-46ed-b762-eb2c63c646c4",
                     "pulp2_distributor_repository_ids":[
                        "9084e06f-8a31-46ed-b762-eb2c63c646c4"
                     ]
                  }
               ],
               "pulp2_importer_repository_id":"9084e06f-8a31-46ed-b762-eb2c63c646c4"
            },
            {
               "name":"myview-3-2",
               "repository_versions":[
                  {
                     "pulp2_repository_id":"1-myview-v1_0-9084e06f-8a31-46ed-b762-eb2c63c646c4",
                     "pulp2_distributor_repository_ids":[
                        "1-myview-library-9084e06f-8a31-46ed-b762-eb2c63c646c4"
                     ]
                  }
               ]
            }
         ]
      }
   ]
}

Here's the traceback it throws:
