[Vuejs]-Vuejs undefined property error but it is defined

✅

You are using an arrow function for your isHttps computed. In that context, this refers to window not the Vue instance, so you will get a cannot read property of undefined message, the correct ES2015 syntax is:

isHttps() { 
  return this.config.scheme === 'https'
}

That is also the same problem with server: () => this.$store.state.server which should be:

server() { 
  return this.$store.state.server
}
