updateAsync in a POST context

[raym]

Although I've used updateAsync to send updates to messenger, I told when used in a POST context that came from a shareAsync I can add a reply to a post. 

I'm posting here to see if anyone has done this successfully and find out what I'm missing. 

While in a context from a shareAsync (type POST). I execute the following updateAsync. The updateAsync is successful but nothing shows up on the post.

 

FBInstant.updateAsync({

action: 'CUSTOM',

image: 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAADUlEQVR42mP8z8CwHwAExQHAgpnk/QAAAABJRU5ErkJggg==',

template: 'UPDATE_SHOWROOM',

text: 'Purple? 76',

})

.then(() => {

console.warn('updateAsync() success!');

})

.catch((err) => {

console.error('updateAsync() ERROR! ', err);

});

 

Any advice?

@raym I am not sure that is supported.

2 things I would do:
1- Make sure the base64 image is valid
2- If that is not the source of the issue, could you create a bug report here? https://developers.facebook.com/support/bugs/. They will let you know if it is the expected result.
