Issue with FBInstant.ShareAsync

[Lawbirth]

Hi,
I'm trying to use FBInstant.ShareAsync from a game made with Unity.
My function is
 

ShareAsync: function (base64Picture, text) {
      var img = Pointer_stringify(base64Picture);
      FBInstant.shareAsync({
      intent: 'REQUEST',
      image: img,
      text: Pointer_stringify(text),
      data: { myReplayData: '...' }
    }).then( function()
    {
        console.log("sharing is done");
    })
    .catch( function(err)
    {
       console.log('failed to share: ' + err.code + " :: " + err.message);
    });
  }

I can correctly see the image but no text appears, and I have three errors in the console repeating:
"POST https://www.facebook.com/react_composer/logging/ods/?event=bootload_start&attachment_type=MEDIA 404".
I've tried also with static string for both text and image, but nothing change.

Any advice? Thanks in advance.

Hi @Lawbirth
What happens if you hardcode the text? I feel like the issue is with Pointer_stringify.

Hi @Noel, thank you for your reply. 

Unfortunately I've alredy tried with hardcoded text, but the result is the same.

Pointer_stringify is necessary, according to https://docs.unity3d.com/Manual/webgl-interactingwithbrowserscripting.html , without this you obtain a pointer, which is not what is needed.

@Lawbirth
What I meant by hardcoding it was something like this:

image: img,
text: 'Test to see is the problem is with Pointer_stringify',
data: { myReplayData: '...' }

@Noel
Yes, sorry. Maybe I didn't explain myself correctly.
I mean, I've tried with harcoded text.
Also, when the text is not hardcoded, Pointer_stringify is necessary.
Those are two separate tests.
So hardcoded text, without Pointer_stringify, does not work as well.

I've also noted, on iOS from messenger app and facebook app the text is showed correctly, so it doesn't work only on android and desktop browser.

@Lawbirth You might want to ask this question to our dev community, maybe someone else had it before and solved it: https://www.facebook.com/groups/instantgamedevelopers/
