Description

The Google Chat app created following the steps in "Build a Google Chat app with Google Apps Script" https://developers.google.com/workspace/chat/quickstart/apps-script-app is not working. It displays "No response from app". The same result occurs even after creating a new Google Cloud project.

The logs show the following:

{
  "insertId": "",
  "jsonPayload": {
    "error": {
      "code": 3,
      "message": "Can't post a reply. The Chat app didn't respond or its response was invalid. See \"Receive and respond to Google Chat events\" (https://developers.google.com/chat/api/guides/message-formats)."
