What type of dict is this action looking for?

[Susanthab]

I'm trying to use aws.autoscaling_create_or_update_tags action and for the Tags parameter it is expecting a dict type. I tried every possible combination but every time it failed with the following error.

Invalid type for parameter Tags[0], value: '[{'Name': 'virtualization-type'}]', type: <type 'unicode'>, valid types: <type 'dict'>

This seems like a bug.
