When trying to publish a post containing link information in the message, the post is successfully published, but the API returns an error response.

As a result, the user cannot confirm the error details and cannot determine whether the post was successfully published or not.

Expected Behavior: If the post is successfully published, I expect a success response instead of an error response.
