Facebook content error when inviting post likes to like page

Have been working with a page, sharing posts into groups (as the page). Getting some engagement and a few post likes, trying to then Invite those into page likes but keep running into the error:

This content is no longer available
The content you requested cannot be displayed right now. It may be temporarily unavailable, the link you clicked on may have expired, or you may not have permission to view this page

But the post is still there in the group, any ideas on what is going wrong?

Thanks

Did you create the post with another profile maybe?

No definitely using the same page on each (using a page not a profile).

Well, today some invites are being sent (and liking the page), others not. I am guessing there is a time break after joining a group before you can invite the post likes to like the page. Or even, the first page you share to a group you cannot send invites on. Will keep trying because I am getting some engagement and page likes now.
