Ways to fix

Summary:

This exception is thrown when the parse function is called on an object of type ModuleArgsParser Class. When creating an instance of that class, there is an optional parameter: task_ds. This parameter is of type dictionary and it looks for certain keys, specifically action and args. The exception is thrown if the value for the key args is a bare String. To avoid this exception, wrap the string value in {{}} within the string itself.

For example: 'args' : '{{a}}'

Code to Reproduce the Error (WRONG):

import ansible.parsing.mod_args as ma
p = ma.ModuleArgsParser(task_ds={'action':'a', 'args':'a'})
p.parse()

Working Version (Fixed):

import ansible.parsing.mod_args as ma
p = ma.ModuleArgsParser(task_ds={'action':'a', 'args':'{{a}}'}) # Notice {{}}
p.parse()
