I am trying to remove a layer from the mapView.

var LayertoRemove=map.findLayerById(layerID);

The layer is found and is actually removed, but after it's removed it continues to throw TypeError: this.controller.destroy is not a function, and the rest of the script is not run. when I remove these two lines of code, the script works fine. the full error log is:

 Uncaught TypeError: this.controller.destroy is not a function   MapView.js:510
at Object.d.detach (MapView.js:510)
at Object.update (MapView.js:25)
at k._animationFrame (init.js:329)

The error in the console is pointing to MapView.js and init.js of the API and not to any line in my script. 

NOTE: The FeatureLayers that I am trying to remove are not hosted layers, but generated from client-side geometries (graphics are created from two csv files taken from the client); I suspect that the error is happening because of the setting of one of the properties of the layer -- which I probably need to set when the layer is created.  map.remove() works fine when I tested it with with a hosted layer. The FeatureLayers are generated as follows and are added to map without any issue:

function createLayer(graphics,renderer,type,fields,title){
lyr = new FeatureLayer({
source: graphics,
objectIdField: "ObjectID",
spatialReference: {wkid: 4326},
geometryType: type,
map.add(lyr);    }
