UDT boolean parameter

Ignition
1

I am using version 8.0.12 and this seemed to work on the previous version 8.0.7.

i have a UDT setup like this

but when i use configure to create the tag the showUser tag is just blank

tag = {
		"name": "error",         
		"typeId" : "Models/Error",
		"tagType" : "UdtInstance",
		"parameters" : {
							"dbErrorCode" : -1,
							"showUser" : True,
							"errorMessage" : None,
							"title" : None
						}
		}
		
system.tag.configure("[myTagProvider]", tag, collisionPolicy="m")

Do I have to do something special when sending a boolean parameter to a UDT?
