FB.ui share_open_graph strange dialog behaviour - facebook

Question

I need to implement URL sharing on Facebook via javascript, sharing also a picture.
When the FB sharing dialog appears, it starts shrinking itself and keeps shrinking more and more until it becomes about 20 pixels wide.
And it happens using either the share_open_graph or "share" method.
Also, on the JS console i see this error when the sharing dialog appears:
ErrorUtils caught an error: "<![EX[["Could not find element \"%s\"%s
from module \"%s\"","u_0_18","","__el...".
Subsequent errors won't be logged; see https://fburl.com/debugjs.
This is my code:
<script>
$(document).ready(function() {
$.ajaxSetup({ cache: true });
$.getScript('//connect.facebook.net/en_US/sdk.js', function(){
FB.init({
appId: '476337039102253',
version: 'v2.8'
});
FB.getLoginStatus(APP.fbUpdateStatusCallback);
});
});
</script>
<button id="itb" class="btn btn-primary btn-large active_down" name="btn" onclick="
FB.ui({
method: 'share_open_graph',
action_type: 'og.shares',
action_properties: JSON.stringify({
object: {
'og:url': 'https://example.com',
'og:title': 'page title',
'og:description': 'desc',
'og:image': 'https://savebybooking.s3.amazonaws.com/public/prd/File_341'
}
})
}, function(response){
if (response && !response.error_message) {
console.log('fb sharing OK: '+JSON.stringify(response));
} else {
console.log('Not OK: '+JSON.stringify(response));
}
}); return false;" type="submit">Share</button>
Are you having the same issue? Why is it happening?
I used the "share" method until yesterday without problems, this issue appeared today with no modification to my code.
p.s. I prefer
using share_open_graph
rather than
share
method because the latter won't let you share the specified picture but seems to pick a random image from the url you are sharing.

Answer 1

This is the error inside of the FB dialog, not inside the page launching the dialog. Also it's because you're missing the meta tags on the page you're sharing. Nothing for FB to scrape for your share.
