typescript开发vue项目二次封装的axios用return Promise.reject(error) 返回异常，提示[Vue warn]: Error in v-on handler (Promise/async)

二次封装axios时刻意服务端模拟了延迟返回数据的场景，用return Promise.reject(error) 返回异常，报如下错误，

[Vue warn]: Error in v-on handler (Promise/async): "Error: timeout of 5000ms exceeded"

export default class Page1 extends Vue {
  private async getList() {
    const {data,pagination} = await getArticles(this.listQuery)
    console.log('data: ',data)
    console.log('pagination: ',pagination)
  }
}

解决办法：用 try{} catch(e){} 包裹处理方法

export default class Page1 extends Vue {
  private async getList() {
    try {
      const {data,pagination} = await getArticles(this.listQuery)
      console.log('data: ',data)
      console.log('pagination: ',pagination)
    } catch (e) {
      console.log(e.message)
    }
  }
}
