node.js - 请求 URL 未从交互式按钮中按下 松弛按下

Question

我想创建一个 slack 应用程序来侦听用户发布的消息，然后在频道中使用一些建议和按钮为该用户回复一条短暂的消息。我有一个订阅事件 API 的 lambda，它正在接收发布的每条消息。我设置了另一个 lambda 来发布临时消息，当我从邮递员（通过 API 网关）调用它时，它成功了，但是当我尝试按下按钮时出现错误：this app responded with a 400 status code

我已经在我的 slack 应用程序的交互部分中指定了请求 URL，该 URL 与用于调用首先发送消息的 Lambda 的 URL 相同。当我检查日志时，我得到了邮递员的第一次点击，但在按下按钮后，我不再收到任何 ping。

我很茫然，不知道从哪里开始，我阅读并重新阅读了 slack 文档并检查了许多堆栈溢出帖子，但没有一个帮助我找到答案。任何帮助将不胜感激。

发送消息的 Lambda：

const axios = require('axios')

exports.handler = async (event) => {
    // TODO implement
    console.log("Request: ", event)
    const response = {
        
        statusCode: 200,
    };
    

    let params = {
        "channel": "hardcoded_channelID",
        "user": "hardcoded_userID",
        "text": "Hello World",
        "blocks": [
