Facebook share button issue: "Attachment not found: The attachment could not be found."

Question

I followed the instructions on this page: https://developers.facebook.com/docs/plugins/share-button/#settings

And i get a working share dialog, but when i try to share to "Share in a private message", i get the following error in the share dialog: "Attachment not found: The attachment could not be found."

My application is an angular 11 application, and i have this in my index.html, right after the body tag:

    <div id="fb-root"></div>
    <script>(function(d, s, id) {
    var js, fjs = d.getElementsByTagName(s)[0];
    if (d.getElementById(id)) return;
    js = d.createElement(s); js.id = id;
    js.src = "https://connect.facebook.net/en_US/sdk.js#xfbml=1&version=v3.0";
    fjs.parentNode.insertBefore(js, fjs);
    }(document, 'script', 'facebook-jssdk'));</script>

The button html looks like this:

<div *ngIf="fbShareRoute" class="fb-share-button" [attr.data-href]="fbShareRoute" data-layout="button" data-size="large"><a target="_blank" href="https://www.facebook.com/sharer/sharer.php?u=https%3A%2F%2Fwww.free-sudoku-puzzle.net%2F&amp;src=sdkpreparse" class="fb-xfbml-parse-ignore">Share</a></div>

My initial thought was that the fb script is not playing along nicely with angular, by the fact that i am binding the url via [attr.data-href], but i dont think this is the case:

• the dialog works ok when simply sharing to your profile
• i tried removing [attr.data-href] and just using a hardcoded data-href attribute, and this made no difference.

Any ideas?

Answer 1

Same here.

I think it's FB bug (OR they purposely disabled attachment/link sharing for certain accounts).

There was a major outage recently in FB messenger as well: https://developers.facebook.com/status/dashboard/

Answer 2

This is a new bug/development. I had share buttons sharing to FB PM's perfectly fine until about the same time as you posted this.
