How do I use system.tag.configure to send a dataset as a parameter to a dataset memory tag in a UDT?

Right now when I send the dataset from my table I get the following error:

I haven’t switched to Ignition 8 yet so I can’t test this right now. Try contacting support if no one else chimes in

I switched from sending parameters to the UDT to just configuring the tag without parameters and then immediately writing the values to all the tags within the instance after configuration. Seems to work just fine.
