Solution to Vue.js TypeError: Cannot set property 'render' of undefined

Developing a Vue.js app and I was getting this:

Uncaught TypeError: Cannot set property 'render' of undefined
    at normalizeComponent (componentNormalizer.js:24)
    at Module../src/App.vue (App.vue?180a:8)
    at __webpack_require__ (bootstrap:766)
    at fn (bootstrap:129)
    at Module../src/main.ts (Scorecard.vue?c458:1)
    at __webpack_require__ (bootstrap:766)
    at fn (bootstrap:129)
    at Object.0 (Home.vue?3d6e:1)
    at __webpack_require__ (bootstrap:766)
    at bootstrap:901

Turns out I accidentally removed the export from my App.vue file.

To solve, open your App.vue file and make sure App is being exported.

<script lang="ts">
export default &#123;
  name: 'App'
&#125;;
</script>
