[3333] SocketCluster socket hung upp, application crashes

I'm trying to implement my Socketcluster server. However when visiting the page the development server of Nuxt crashes.

I made the Socketcluster client plugin myself:

import Vue from 'vue'
import scc from 'socketcluster-client'

const SCPlugin = {
  install(Vue, options) {
    Vue.prototype.$sc = scc.create(options)
    Vue.mixin({
      mounted() {
        console.log('sc plugin mounted')
      }
    })
  }
}

const options = {
  hostname: 'localhost',
  secure: false,
  port: 8000
}

export default () => {
  Vue.use(SCPlugin, {
    options
  })
}

and injected it to the nuxt.config.js

 plugins: [
    '@/plugins/socketcluster.js'
  ],

I'm fairly new to Nuxt. Therefore I don't really understand where the issue might lay. In regular Vue development this works.
