Protoype Error Loading Map

[KarlMcCollesterGP]

Using Webpack with Rails 5/StimulusJS to load a map in an application.  webpack config:

new ArcGISPlugin({
    // exclude 3D modules from build
    features: {
        locales: ['en','es'],
        "3d": false
    }

 stimulus controller:

import {Controller} from "stimulus"
import esriConfig from '@arcgis/core/config';
import esriMap from "@arcgis/core/WebMap";
import mapView from "@arcgis/core/views/MapView"

export default class extends Controller {
    connect() {
        esriConfig.apiKey = "<APIKEY>";

        const map = new esriMap({
            basemap: "topo-vector" // Basemap layer service
            // basemap: "streets-navigation-vector"
        });
        const view = new mapView({
            map: map,
            center: document.getElementById("jurisdiction-centerpoint").innerText.split(","), // Longitude, latitude
            zoom: 13, // Zoom level
            container: "map-search-results" // Div element
        });

    }}

The map control loads with a generic background tile and the following error in console:

TileInfoViewPOT.js:55 Uncaught TypeError: Cannot read property 'prototype' of undefined
at t.getTileCoverage (TileInfoViewPOT.js:55)
at a.update (TileManager.js:79)

Any help is appreciated!
