Failed to unlike comment

Error message

Failed to unlike comment

What it means

comments.unlike() DELETEs /members/api/comments/{comment.id}/like with a body of {comments: [comment]} to remove a like. Returns 'Success' on ok, throws on non-ok. The DELETE-with-body pattern is unusual but matches this API's convention.

Solutions

1. Check the Network tab DELETE response status.
2. Optimistically toggle the UI and revert on error; debounce the button.
3. If 404, sync local state to 'not liked' since the like or comment no longer exists.
4. If 401, re-authenticate before retrying.

setLiked(false);
try {
  await api.comments.unlike({comment});
} catch (e) {
  setLiked(true); // roll back
  if (e instanceof Error && e.message === 'Failed to unlike comment') {
    // sync state from server
  }
}

When it happens

Trigger: The DELETE returns 4xx/5xx. The member did not previously like the comment (may be 404/409), the session expired (401), the comment was deleted (404), or the server errors (5xx).

Common situations: A member removes a like on a comment that was deleted server-side. A session expiry mid-session. A race where the like was already removed by another tab/request.
