RoutingTask Error 9004$LAYER_NOT_EXIST

wcESRI — Sun, 12 Dec 2021 16:23:49 GMT

Hello,

I am attempting to solve a route. My code is below.

To create my service, I added the following URL to my ArcGIS Online content.

I then made it accessible to everyone and used the REST URL in my code.

//prepare parameters
 var myRouteParams = new RouteParameters();
 myRouteParams.stops = new FeatureSet();
 myRouteParams.stops.features.push(myStartingGraphic);
 myRouteParams.stops.features.push(myEndingGraphic);
 myRouteParams.returnRoutes = true;
 myRouteParams.returnDirections = true;
 myRouteParams.outSpatialReference = new SpatialReference({ wkid:4326 });
      
 //perform route between addresses  
 var myRouteTask = new RouteTask("url_goes_here");       
 myRouteTask.solve(myRouteParams);

However, I get the following error in the debugger.

dojo.io.script error Error: 9004$LAYER_NOT_EXIST

"dojo.io.script error"

[object Error]{code: 500, description: "", details: Array[0], httpCode: 500, log: undefined, message: "9004$LAYER_...", name: "Error", number: 0}

What is causing this error? Do I need something else in my routing parameters?

Christopher,

When you try to browse to the layer you linked I get

I noticed that. However, is something supposed to be listed?

I am also not sure what URL to use.

Christopher,

You are right.

This example works with the same route layer you provided above.
