When we have array values on the services invoker, we need to pass comma separated values, and we should be able to pass array json syntax as well.

Example:

This one works:

{
    "/assetvocabulary/get-vocabularies": {
		vocabularyIds: '10436,10437'
	}
}

This one doesn't work:

{
    "/assetvocabulary/get-vocabularies": {
		vocabularyIds: [10436,10437]
	}
}

Not only for arrays, we should be able to pass JSON object for object arguments, too. For example, to create some object, we should be able also to pass JSON object string.
