Error message

Reply not found.

What it means

GraphQL mutation updateReply (resolver.ts:202) throws ReplyNotFound when service.getReply(input.id) returns null. The reply (comment sub-item) does not exist; the check runs before 'Doc.Comments.Update' permission and before service.updateReply.

Solutions

1. Refetch the thread and only edit replies still present.
2. Treat a vanished parent comment as removing all its replies; drop local reply state with it.
3. Keep the reply editor bound to a live subscription so deleted replies disable editing immediately.

const replyAlive = (await comments(docId)).some(c => c.replies?.some(r => r.id === input.id));
if (!replyAlive) { /* disable edit action */ }

function isReplyNotFound(e: unknown): boolean {
  return (
    e instanceof GraphQLError &&
    (e.extensions?.code === 'reply_not_found' ||
      e.message === 'Reply not found.')
  );
}

try {
  await updateReply({ id, content });
} catch (e) {
  if (isReplyNotFound(e)) {
    // reply (or its parent) is gone: refetch thread, drop stale editor
  } else throw e;
}

When it happens

Trigger: Calling updateReply with a reply id that is deleted or unknown - e.g. the parent comment (and its replies) was deleted while the reply editor was open.

Common situations: Editing a reply in a thread that a collaborator deleted (deleting a comment removes its replies); stale reply id from an outdated subscription snapshot.

Background: "Not found" and "does not exist" errors: why "Task not found", "No such folder", and "Can't find" fire when a lookup comes back empty — this error's family across 14 libraries.
