Facebook denied CoSchedule's request to send this message. Facebook does not allow you to share Facebook event links with their API.
Why did I receive this error?
Facebook does not allow sharing of links to Facebook Events through their API (more info on that at "
API and Other Platform Product Changes"). This affects CoSchedule as well as all other third-party applications.
What should I do to resolve this?
To resolve this issue you will have to share the event directly on Facebook. Or as an alternative, you could try using an image-type message and include a link to the event in the body of the message.
How do I prevent this error from happening in the future?
The only way to avoid this issue is to not share links to Facebook Events in messages you schedule through CoSchedule.
