获取类型错误：o 不是 laravel 和 vue 2.6.14 项目上的函数

Question

我得到 typeError: o is not a function 当我运行 npm run prod 但是当我运行 npm run dev 我不明白

它发生在实时服务器和开发中

我的代码

export default {
  name: "CreateTimesheet",
  props: ["employees", "creatorId"],
  mounted() {
    this.employee_id = this.creatorId;
    this.getProjects();
  },
  data: () => {
    return {
      employee_id: 1,
      project_id: 0,
      projects_dropdown: [],
    }
  },
  methods: {
    async getProjects() {
      try {
        const res = await fetch('/getclientprojects/'+this.employee_id).then(response => response.json());
        this.projects_dropdown.push(...res.projects)
        this.project_id = res.active_projects // It happens when i add this line
      }catch (e) {
        console.log(e)
      }
    }
  }
}
</script>```
