set tTaskResponce = %request.Content.Task Raises Property Does Not Exist

[railrhoad]

Located within PostTask, we're getting a PropertyDNE on *Task. We have the other service behaving as expected in our REST client but we're now at the point where we'd like to perform updates.

{
	"errors":[ {
			"code":5002,
			"domain":"%ObjectErrors",
			"error":"ERROR #5002: Cache error: <PROPERTY DOES NOT EXIST>zPostTask+5^eReferral.REST.Services.1 *Task,%CSP.BinaryStream",
			"id":"CacheError",
			"params":["<PROPERTY DOES NOT EXIST>zPostTask+5^eReferral.REST.Services.1 *Task,%CSP.BinaryStream"
			]
		}
	],
	"summary":"ERROR #5002: Cache error: <PROPERTY DOES NOT EXIST>zPostTask+5^eReferral.REST.Services.1 *Task,%CSP.BinaryStream"
}

%request.Content is a CSP.BinaryStream, what I don't understand is how %request.Content.Task gets populated. I can understand what's getting passed in will directly influence the Content but I don't even see how this Task serialization happens within the service (as I try to debug this).

Here's my input to the service which is JSON valid and appears to be schema valid based on the sample input provided in the readme:

	"_class": "EnsLib.Workflow.Worklist",
	"_id": "1208||ereferraladmin",

I even passed in the JSON from the readme (which I knew wouldn't find the task referenced) but it failed in the same place before it could even look it up.

You're getting an error here because %request.Content is %CSP.BinaryStream but EnsLib.Workflow.Worklist is expected. Conversion from %CSP.BinaryStream is done in ConvertRequestBody. Seems like it's not hit for you.

Please provide:

1.$zv
2. Does adding do ..ConvertRequestBody() before set tTaskResponce = %request.Content.Task and recompiling helps?
3. Does Workflow.AbstractREST compile without problems?

You're exactly right! I was cherry picking into my preexisting service and simply missed this line. Sorry for the noise and thanks for the quick response!
