POST API call to Chat V1 messages not working

Thanks for stopping by to ask us a question! Please make sure to include:

• What you're trying to do

Trying to follow documentation in how to request extra configurations to the user, I'm following the docs to use ActionResponse but when I use the client I get Error: Message cannot be empty. and if I try the API using fetch I get 400 Bad Request. Hoping I get this

but I'm not getting anything

• What code you've already tried

I've tried the following using the client

   import { chat, auth } from '@googleapis/chat';
   
   const googleAppAuth = new auth.GoogleAuth({
     // Specify required scopes.
     scopes: ['https://www.googleapis.com/auth/chat.bot'],
   });
   const chatAppClient = await chat({
      version: 'v1',
      auth: googleAppAuth,
   });

    chatAppClient.spaces.messages.create({
        parent: space,
        requestBody: {
          actionResponse: {
            type: 'REQUEST_CONFIG',
            url: 'https://google.com',
          },
        },
      });

and using raw api call:

    const token = await googleAppAuth.getAccessToken();
    console.log(await fetchEndPoint(`https://chat.googleapis.com/v1/${eventData.space?.name}/messages`, {
      body: JSON.stringify({
        actionResponse: {
          type: 'REQUEST_CONFIG',
          url: 'https://google.com',
        },
      }),
      method: 'POST',
      headers: {
        Authorization: `Bearer ${token!}`,
      },
    }));

googleAppAuth is using ADC with the chat scope.

• Any error messages you're getting

PLEASE READ: If you have a support contract with Google, please create an issue in the support console instead of filing on GitHub. This will ensure a timely response.

Comienza con la documentación enlazada de ActionResponse y compárala con la llamada chatAppClient.spaces.messages.create y el ejemplo de fetch POST /v1/{space}/messages. Reproduce las respuestas reportadas “Message cannot be empty” y 400 y, a continuación, determina el comportamiento esperado de la solicitud y documenta o resuelve la discrepancia.
