          ...
        },
        tokenRequired: false, // set false
      },
    },
  }

./lib/schemes/local.js

  async fetchUser (endpoint) {
   ...
    
    // maybe the request return not 200 status
    const user = await this.$auth.requestWith(
        this.name,
        endpoint,
        this.options.endpoints.user
      )
    this.$auth.setUser(user)
