Facebook Autopublish Error

Please make sure that your app has pages_manage_posts, pages_read_engagement permissions.
If your app has permissions then please remove the app from business integrations at Facebook settings(https://www.facebook.com/settings?tab=business_tools)
and reauthorize after it.
If the app is live then without permission it won’t work.

There are similar bug reports at Facebook Platform Bug Reports( https://developers.facebook.com/support/bugs/999600563832125/)
If reauthorizing the app won’t work for you please report it to Facebook at https://developers.facebook.com/support/bugs/

Hope this helps.

These issues are not happening all the time. But happens to random posts. So if it is random then it’s not related to any Facebook permissions I belive
