This is generated data

{
	"data": [{
		"parent": "gateway",
		"child": "smartccp",
		"callCount": 2
	}, {
		"parent": "gateway",
		"child": "",
		"callCount": 8
	}, {
		"parent": "gateway",
		"child": "smartprovision",
		"callCount": 6
	}, {

		"callCount": 122
	}],
	"total": 0,
	"limit": 0,
	"offset": 0,

}

then I got a console error when I click the [Jaeger UI/System Architecture/DAG] link

Error: Can not create element with invalid string ID ``

and my [Force Directed Graph] is also is weird like this

Duplicate Node ?

@everett980 is this UI issue? The child node's service name is an empty string that is causing an error in the UI.
