TypeError: unhashable type

The "type" name of the parameter generates an error when formatting the scenario json.
The scenario is incomplete, the field "type":"command.CommandAction.xx", is missing in json.

If I replace the parameter name by another, There is no longer the issue.

Same issue on 0.5.3.and 0.6
