Failed to dislike comment

Error message

Failed to dislike comment

What it means

comments.dislike() POSTs to /members/api/comments/{comment.id}/dislike to register a dislike reaction. Mirrors the like() structure: returns 'Success' on ok, throws on non-ok, no body sent. Dislike is a labs-gated feature in Ghost comments.

Solutions

1. Check the Network tab POST response status and body.
2. Gate the dislike button visibility on the labs flag returned by site.settings() to avoid 403s.
3. Optimistically update and revert on error; disable the button during the request.
4. If 401, re-authenticate; if 403, hide the dislike UI and refresh settings.

function isDislikesEnabled(labs: {dislikes?: boolean} | undefined): boolean {
  return Boolean(labs?.dislikes);
}

setDisliked(true);
try {
  await api.comments.dislike({comment});
} catch (e) {
  setDisliked(false);
  if (e instanceof Error && e.message === 'Failed to dislike comment') {
    // if 403, dislikes may be disabled — refresh labs
  }
}

When it happens

Trigger: The POST returns 4xx/5xx. The member is unauthenticated (401), already disliked (409/400), the comment was deleted (404), the labs flag for dislikes is disabled (403), or rate limited (429).

Common situations: A member dislikes a comment but the site admin disabled the dislike labs feature after the UI rendered the button. Session expiry. A double-click submits two dislikes.
