post 'attached_media' array

[Art3miX]

I was trying to post a post to Facebook with multiple images, but facebook was giving me error when I was adding attached_media parameter to the ${pageId}/feed, This is how I ended up doing it:

const postData = {
  message:        post.text,
};

images.forEach((imageId, index) => {
  postData[`attached_media[${index}]`] = `{"media_fbid": "${imageId}"}`
});

Looping over all the images, and manually adding attached_media[index] parameter.

It would be nice if we could just add it as an array, like this:

const postData = {
    message:        post.text,
    attached_media: [{"media_fbid": "${imageId1}"}, {"media_fbid": "${imageId2}"}]
};

Hey @Art3miX
I tried to post multiple images to my facebook page using your first method but i am getting an error. This is the data i'm sending

postData =  {
  caption: 'hello',
  'attached_media[0]': '{"media_fbid": "01"}',
  'attached_media[1]': '{"media_fbid": "02"}'
}

and this is the request i'm sending

        const b = await FB.api("me/photos", "post", postData);

and this is the error i'm getting

 response: {
    error: {
      message: '(#324) Requires upload file',
      type: 'OAuthException',
      code: 324,
      fbtrace_id: 'ANWCN2qEmLMW6-h-afDPMAy'
    }
  }

That was a long time ago, but I think you first need to upload the images, and use the given imageId in your post.
Note my first snippet, i do a loop over the uploaded images, and add them to the postData.

Thanks for the reply. I appreciate
I did upload the images and received the ids back
I also added the Ids to postData just like you did in the first snippet
But for some reason i keep getting an error

After a bunch of trial and error , i fixed it!
In case anyone comes here from the future , heres what i did

When you make the first request you get an id and a post_id , Capture the ID NOT THE POST_ID

 const firstRequest = await FB.api("me/photos?published=false", "post", {
              source: fs.createReadStream(
              "{image-path}"
              ),
            });

Capture the Id's and store them in exactly this format

postData =  {
  caption: 'hello',
  'attached_media[0]': '{"media_fbid": "01"}',
  'attached_media[1]': '{"media_fbid": "02"}'
}

Send the final request to post to your page

 const secondRequest = await FB.api("me/feed", "post", postData);

Hope this helps someone
Also thanks for your time @Art3miX
