‼ Error message:
Links to Facebook posts, groups or profiles can't be shared.
📔 Explanation:
Facebook does not allow sharing of links to Facebook Events through the API.
✅ Solution:
You can share the event link directly on facebook.
Another workaround is to only share the link to the event in the post content without the preview
Create a social post to facebook
Add the event link in the post content
A preview will be automatically created and attached to the post
Click the delete button to remove it
Now you can publish the post with a link to the event
You can attach a story/image/video or another valid link to the post if you want.
