i have follow along the documentation on https://firebase.nuxtjs.org/ but when try to use the this.$fire.auth.createUserWithEmailAndPassword(email, password) i got same error like below

here is my code

  async userRegister({ email, password }) {
      try {
        this.error = null
        this.set_loding(true)
        await this.$fire.auth.createUserWithEmailAndPassword(email, password)
        this.$nuxt.$loading.finish()
        this.$router.push('/')
      } catch (err) {
        this.set_loding(false)
        this.$nuxt.$loading.finish()
        this.alert = true
        this.error = err.message
      }
    },
