如何传递多个突变来更新 Vuex 存储？

Question

如果我只改变状态一次（通过提交下面显示的两个改变中的任何一个），没有错误并且图表被正确更新。如果我运行两个突变：

commit('SET_COURSE_MATERIAL', data)
commit('SET_TOOLS_EQUIPMENT', data)

然后我得到 Maximum call stack exceeded: RangeError。

如果我在chart.vue的手表属性中注释掉代码，没有错误，我可以在console.log

中看到具有正确值的状态

仅当我运行 "npm run dev" 时，我才收到有关最大调用堆栈的错误。当我将它部署到 Google 云时，该站点按预期工作并且我没有收到任何错误。我什至通过编辑一些代码并重新部署它两次来重新检查它，同时还注意到构建日志中的时间。

深度复制图表配置。

methods: {
    drawChart() {
      this.handler.$emit('init', {...this.chartConfig})
    }
  }
