Hi,

I changed to use ArcGIS JS 4.10 API and noticed that I cannot remove WMTS layer from view.map

console.log shows:

Uncaught (in promise) TypeError: Cannot set property 'visible' of null
at Object.<anonymous> (MapView.js:603)
at b.callback (dojo.js:365)
at b.notify (dojo.js:325)
at b.propertyInvalidated (dojo.js:326)
at b.propertyInvalidated (dojo.js:298)
at b.callback (dojo.js:330)
at b.notify (dojo.js:325)
at b.propertyCommitted (dojo.js:327)
at b.propertyCommitted (dojo.js:299)
at b.internalSet (dojo.js:297)

I have attached example file. Changing active layer to another will trigger the remove operation which causes the problem.

This was working on ArcGIS JS API 4.9 and this problem occurs only with WMTS layers. Please provide a fix as soon as possible.

UPDATE:

Found a workaround. Set layer visible to false on WMTS layer before removing it from the MapView then it does not cause the crash.

Br,

Markus
