Cannot read property 'run' of undefined (awesome-typescript-loader) - npm

Question

I'm attempting to update our angular 5 application to angular 6, and am running into a build issue currently with awesome-typescript loader.
The full error message is
C:\source\ProjectFolder\Angular.Web.App\node_modules\awesome-typescript-loader\src\watch-mode.ts:5
compiler.hooks.run.tapAsync('at-loader', function(params, callback) {

it is required, as our webpack is pulling in its CheckerPlugin
const CheckerPlugin = require('awesome-typescript-loader').CheckerPlugin;
module.exports = (env) => {
// Configuration in common to both client-side and server-side bundles
const isDevBuild = !(env && env.prod);
const sharedConfig = {
stats: { modules: false },
context: __dirname,
resolve: { extensions: [ '.js', '.ts' ] },
output: {
filename: '[name].js',
publicPath: 'dist/' // Webpack dev middleware, if enabled, handles requests for this URL prefix
},
module: {
rules: [
{ test: /\.ts$/, use: isDevBuild ? ['angular2-template-loader', 'angular2-router-loader'] : '#ngtools/webpack' },
{ test: /\.html$/, use: 'html-loader?minimize=false' },
{ test: /\.css$/, use: [ 'to-string-loader', isDevBuild ? 'css-loader' : 'css-loader?minimize' ] },

};
currenlty using awesome-typescript-loader v. 5.0.0
