Mistral unable to initialize custom action class

[Sonal]

I am using liberty version of Mistral, and its logs shows following error message when trying to create an execution.

Failure caused by error in task 'xxxxx': Failed to initialize action xxxxx. Action init params = ['auth_url', 'admin_domain_name']. Actual init params = [u'auth_url', u'admin_domain_name']. More info: 'type' object does not support item assignment.

The workflow is a custom direct workflow and the action are custom actions which are available under the pythonpath /usr/lib/python2.7/site-packages/

The error seems to be happening in the file https://github.com/openstack/mistral/blob/stable/liberty/mistral/engine/default_executor.py#L60
