[2557] Unable to access Store in mounted hook after page refresh

This is on a page. I am logging for this.$store. The store works when you click around but when i refresh the page the store is blank.

  mounted () {
    console.log(this.$store.getters.getCartId) 
    axios.get(url + this.$store.getters.getCartId).then(res => {
      // do something
    })
  }
