Has anyone used "findLayerByID" with success?

Paco

Hello again all.    I am still having problems accessing individual layers within my WebMap thru the js API.

if I have loaded an existing webmap visually in my app-

const webmap = new WebMap({

  portalItem: { // autocasts as new PortalItem()

    id: "xxportalIDxx"

  }

});

 

why can't I access the individual Layers within it by their IDs?   i've tried-

 

const newLayer = webmap.findLayerByID('xxlayerIDxx')

 

but keep getting- 

 

TypeError: webmap.findLayerByID is not a function

 

shouldn't this be a basic chore,  to access individual layers within a WebMap?

 

thx!

I think you have a typo. It's findLayerById.

You need to either wait for view.when() or call the webmap.loadAll(), both are promises so you can await them or use promise.then().
