I created a facebook instant game and in the end there's a share button, how to make that share button shares the result or a photo in a link to play the game on the player's profile. Here's my code of the shareAsync() function, which produces no javaScript errors but yet doesn't work.

$(document).on("click", ".share-result", function(){ FBInstant.shareAsync({ intent: 'INVITE', image: img, text: 'Play this Awesome game', data: {myReplayData: '...'}, }).then(function() { location.reload(); }); });

A base64Image must be passed in the image object of FBInstant.shareAsync() function. In your case, pass onto your img var. For sample working, img var below has an image of 1.9 kb in the form of base64 code.

var img = "data:image/png;base64,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"; FBInstant.shareAsync({ intent: 'INVITE', image: img, // base64Image code must be passed in img text: 'Play this Awesome game', data: {myReplayData: '...'}, }).then(function() { location.reload(); });

For testing now, use this site to upload your image, convert it to base64 and copy the image code that starts with data:image/ ending in a very long hash. Store the copied code into your variable named img. It must work then.
