Actions On Google Async Issue: Error: No response has been set

Question

在我的 Google Diaglogflow 意图上收到来自以下意图的以下错误。 console.log("res", res) 正确地记录了 JSON，但是 Error: No response has been set. Is this being used in an async call that was not returned as a promise to the intent handler? 记录在它之前。

app.intent(DO_MY_THING, conv => {
  console.log("DO_MY_THING");
  axios
    .get("example.com")
    .then(res => {
      console.log("res", res);
      conv.close("Did the thing");
    })
    .catch(err => {
      console.log("err", err);
      conv.close("didnt do the thing");
    });
});

如果您正在执行异步回调，则需要 return Promise 对象。

app.intent(DO_MY_THING, conv => {
  console.log("DO_MY_THING");
  return axios
    .get("example.com")
    .then(res => {
      console.log("res", res);
      conv.close("Did the thing");
    })
   .catch(err => {
     console.log("err", err);
     conv.close("didnt do the thing");
   });
});
