Embedding Preview - Cannot find module

1

Hello,

I just built Metadata locally (running on a Mac) and am having potential issues with the embedding question preview. It is simply blank. Checking the console errors, I get the following:

Uncaught Error: Cannot find module "."
at webpackMissingModule (app-embed.bundle.js:11175)
at EmbedFrame.componentWillMount (app-embed.bundle.js:11175)
at ReactCompositeComponentWrapper.performInitialMount (vendor.bundle.js:111371)
at ReactCompositeComponentWrapper.mountComponent (vendor.bundle.js:111278)
at Object.mountComponent (vendor.bundle.js:57060)
at ReactCompositeComponentWrapper.performInitialMount (vendor.bundle.js:111391)
at ReactCompositeComponentWrapper.mountComponent (vendor.bundle.js:111278)

at ReactCompositeComponentWrapper.performInitialMount (vendor.bundle.js:111391)
at ReactCompositeComponentWrapper.mountComponent (vendor.bundle.js:111278)

Looking further into the app-embed.bundle JS file, I see this:

_createClass(EmbedFrame, [{
        key: "componentWillMount",
        value: function componentWillMount() {
            var _this2 = this;

            if (window.iFrameResizer) {
                console.error("iFrameResizer resizer already defined.");
            } else {
                window.iFrameResizer = {
                    autoResize: true,
                    heightCalculationMethod: "bodyScroll",
                    readyCallback: function readyCallback() {
                        _this2.setState({ innerScroll: false });
                    }
                    // $FlowFixMe: flow doesn't know about require.ensure
                };!(function webpackMissingModule() { var e = new Error("Cannot find module \".\""); e.code = 'MODULE_NOT_FOUND'; throw e; }()).ensure && __webpack_require__.e/* require.ensure */(0).then((function () {
                    __webpack_require__(762);
                }).bind(null, __webpack_require__)).catch(__webpack_require__.oe);
            }
        }

Dropping a breakpoint in there and refreshing yields this:

require.ensure && require.ensure([], () => {
                require("iframe-resizer/js/iframeResizer.contentWindow.js")
            });

Does anyone have any suggestions on how to fix this?

Thanks,
Ryan
