Sentry / Raven not reporting JS errors

Hi there, I have Raven / RavenVue setup in my build but I’m unable to get it to record any errors. Below is my app.js file showing my setup. I’ve been beating my head against a wall trying to figure out why it won’t send any errors up to Sentry.

const app = new Vue({
  components: {
'[filtered]': [filtered]


Raven.config('https://[filtered][filtered]').addPlugin(RavenVue, Vue).install()
