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

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$/, use: [ 'to-string-loader', isDevBuild ? 'css-loader' : 'css-loader?minimize' ] },
                { test: /\.(png|jpg|jpeg|gif|svg)$/, use: 'url-loader?limit=25000' },
                ...sharedModuleRules
            ]
        },
        plugins: [new CheckerPlugin()]
    };

currenlty using awesome-typescript-loader v. 5.0.0
