When I'm trying to run any database migration, every time it is failing at step of edxapp : migrate.

TASK [edxapp : migrate] ******************************************************** failed: [localhost] (item=lms) => {"changed": true, "cmd": ["/edx/bin/edxapp-migrate-lms"], "delta": "0:04:58.188980", "end": "2017-10-26 01:14:15.137864", "failed": true, "item": "lms", "rc": 1, "start": "2017-10-26 01:09:16.948884", "stderr": "2017-10-25 21:09:21,176 INFO 18199 [dd.dogapi] dog_stats_api.py:66 - Initializing dog api to use statsd: localhost, 8125\nTraceback (most recent call last):\n File \"manage.py\", line 116, in <module>\n execute_from_command_line([sys.argv[0]] + django_args)\n File \"/edx/app/edxapp/venvs/edxapp/local/lib/python2.7/site-packages/django/core/management/__init__.py\", line 354, in execute_from_command_line\n utility.execute()\n File \"/edx/app/edxapp/venvs/edxapp/local/lib/python2.7/site-packages/django/core/management/__init__.py\", line 346, in execute\n self.fetch_command(subcommand).run_from_argv(self.argv)\n File \"/edx/app/edxapp/venvs/edxapp/local/lib/python2.7/site-packages/django/core/management/base.py\", line 394, in run_from_argv\n
