Hi guys, I hope you are all doing well!

I have a strange exception in my implementation. The problem is when there is a popup in display, and if I want to zoom out, the Esri Library is throwing an exception. 4.24:2411 Uncaught TypeError: Failed to execute 'removeChild' on 'Node': parameter 1 is not of type 'Node'.

I'm not sure if it is related to my implementation. If required I can also share what I'm doing within JS.

Attaching this as well, maybe it helps.

UPDATE:

I found the problem source. It is the renderer that I have for my sublayers. When I remove them I'm no longer having the exception but I don't understand what is wrong with my renderer:

 

let rluLayer = new MapImageLayer({
                url: URL,
                imageFormat: "png24",
                imageTransparency: "true",
                listMode: "show",
                title: "RLU Program",
                sublayers: [
                    {
                        id: 0,
                        title: "Unavailable RLU",
                        definitionExpression: "Status = 'Available'",
                        visible: true,
                        // renderer: {
                        //     type: "simple",
                        //     symbol: {
                        //         type: "simple-fill",
                        //         style: "solid",
                        //         outline: {
                        //             style: "solid",
                        //             color: [255, 0, 0],
                        //             width: 1
                        //         },
                        //         color: [255, 0, 0, 0.2]
                        //     }
                        // }
                    },
                    {
                        id: 1,
                        title: "Available RLU",
                        definitionExpression: "HuntingID IN (810004, 810005)",
                        // renderer: {

                    }
                ]
            });

Your code does work on this sample. Have you checked whether your layers support dynamic layers?

console.log(layer.capabilities.exportMap.supportsDynamicLayers);

You'll have to put this in the layer.when() function to ensure the layer is ready before you can see this property.

Hi Ken, no, I didn't check that. But it looks like they does. 

> rluLayer.capabilities.exportMap.supportsDynamicLayers
< true
> permitLayer.capabilities.exportMap.supportsDynamicLayers
< true

It would help to have a working app to debug. Are you getting any useful errors in the console? Did you verify that the MapServer supports dynamic layers from REST? E.g.

Hi Noah,

Yes, the MapServer supports dynamic layers. POT:

As for the error message, I attached it to the original post. I only see a Javascript exception but not an indicator of the cause.
