Creation of callback URLs for long-term requests

Hello! I have a Zapier Integration in which some actions (requests to my backend) require more time to respond (up to one minute), and when I'm testing a new Zap with this action, I encounter an error message: 'The app did not respond in time. It may or may not have completed successfully.'

I'm trying to create an action with a callback URL, but I'm not receiving any response at the next step.

Here is my action code:

module.exports = {
  key: "prediction",
  noun: "Prediction",
  display: {
    label: "Create Prediction",
    description: "Creates a new prediction.",
  },
  operation: {
    inputFields: [
      {
        key: "question",
        required: true,
        type: "string",
        helpText: 'Provide a "Yes" or "No" question to ask the Magic 8-Ball.',
      },
    ],
    perform: (z, bundle) => {
      const promise = z.request({
        url: "https://83a7-38-54-105-8.ngrok.io/v1/zapier/test",
        method: "POST",
        body: {
          url: z.generateCallbackUrl(),
        },
        headers: {
          "content-type": "application/json",
          "X-API-Key": "secret",
        },
      });

      return promise.then((response) => ({ ...response.data, extra: "data" }));
    },

    performResume: (z, bundle) => {
      const { extra, ...originalOutput } = bundle.outputData;

      return { ...originalOutput, ...bundle.cleanedRequest };
    },
    sample: {
      callbackUrl: "http://zapier.com/hooks/catch/-1234/abcdef/",
      status: "success",
      result: "Ask again later.",
    },
    outputFields: [
      { key: "callbackUrl", label: "Callback URL" },
      { key: "status", label: "Status" },
      { key: "result", label: "Predicted Result" },
    ],
  },
};

and test request of my API code
 

  @Post('/test')
  async testCallback(@Body('url') url) {
    setTimeout(() => {
      fetch(url, {
        method: 'POST',
        body: JSON.stringify({
          callbackUrl: 'http://zapier.com/hooks/catch/-1234/abcdef/',
          status: 'success',
          result: 'Ask again later.',
        }),
      });
    }, 30000);

    return { callbackUrl: url, status: 'loading' };
  }
