I have a process that reads the Facebook pages available to a user. It looks for a specific page and then will post to that page, using that pages page_token and the Providers/facebook/pages/publish.aspx endpoint. I'm able to retrieve the page_token fine, so I know that manage_pages and other facebook settings/permissions are correct.
When I try to publish, the API returns a 500 error with the following description:
"An unknown error has occurred while trying to post your message. Please try again in a few minutes"
Anyone else have this issue?
