Cannot get a layer to appear on map

This is my first time using the ArcGIS API for JavaScript. I'm running into a fairly elementary error. I cannot get a layer I have hosted on ArcGIS Online to appear on the map. Here is my code:

require([

"esri/config",

"esri/Map",

"esri/layers/FeatureLayer",

"esri/views/MapView"

], function (esriConfig, Map, MapView, FeatureLayer) {

//Setting the API key

esriConfig.apiKey = api key hidden

const map = new Map({

basemap: "arcgis-topographic"

});

const view = new MapView({

container: "viewDiv",

map: map,

extent: {

xmin: -88.4407865369763,

ymin: 44.2519512604157,

xmax: -87.57033074655209,

ymax: 44.58559644055305,

spatialReference: 4326

});

let one_year_high = new FeatureLayer({

url: "https://services.arcgis.com/HRPe58bUyBqyyiCt/ArcGIS/rest/services/1_year_high_lake_level/FeatureServer/13",

id: "1-year-high",

apiKey: api key hidden

});

map.add(one_year_high);

});

This script produces the following error in my browser:

[esri.Map] #add() The item being added is not a Layer or a Promise that resolves to a Layer.

My layer can be found here: https://services.arcgis.com/HRPe58bUyBqyyiCt/ArcGIS/rest/services/1_year_high_lake_level/FeatureServer/13

I can't figure out why it won't appear.

Thanks in advance.

In your require and function, the MapView and FeatureLayer order are swapped. When using amd, the order matters.
