松弛螺栓清除视图堆栈

Question

在view_submission类型中，我设置ack以清除堆栈，如下所示：

await submissionAck({ response_action: 'clear' } as any)

第一个问题-为什么我必须将其强制转换为任何？没有它，代码将引发错误

Argument of type '{ response_action: "clear"; }' is not assignable to parameter of type '(ViewUpdateResponseAction & void) | (ViewPushResponseAction & void) | (ViewClearResponseAction & void) | (ViewErrorsResponseAction & void) | undefined'.Type '{ response_action: "clear"; }' is not assignable to type 'ViewClearResponseAction & void'.
Type '{ response_action: "clear"; }' is not assignable to type 'void'.

第二个问题-堆栈似乎未清除。当我第一次提交模态时可以，但是如果我下次尝试时它会抛出：

[ERROR]  bolt-app { Error: The receiver's `ack` function was called multiple times.

有什么想法吗？这就是我所说的这些视图的方式：（顺便提一下，第三个问题-为什么我必须将主体强制转换为BlockAction？否则，它将引发错误，表明trigger_id不存在）]

  app.action('modify', async ({ body, ack }) => {
    await ack()
    await authenticate(body.team.id, async (customer: Customer) => {
      await app.client.views.open({
        trigger_id: (body as BlockAction).trigger_id,
        token: 'token',
        view: modificationModal,
      })
      app.view(
        {
          type: 'view_submission',
          callback_id: 'yay',
        },
        async ({ body: submissionBody, ack: submissionAck, view }) => {
          const receivedValues = submissionBody.view.state.values
          await submissionAck({ response_action: 'clear' } as any)
        },
      )
    })
  })
我知道文档中的立场：

view() requires a callback_id of type string or RegExp.

但是那并不能告诉我很多。那串是什么？那是功能吗？应该怎么办？ 

抱歉给您带来麻烦的问题，谢谢您的帮助！

我将尝试以相反的顺序回答这些问题，因为我认为这可能是最合理的。
