query_too_long

Error message

Query is too long, max length is ${max}.

What it means

Thrown by the realtime workspace members search when input.query exceeds 255 characters — a hard input-size guard before the call to models.workspaceUser.search. Note the asymmetry: pagination.take is silently clamped (1..WORKSPACE_MEMBERS_REQUEST_TAKE_MAX) but an over-long query is rejected outright with QueryTooLong({ max: 255 }).

Solutions

1. Trim and truncate the query to <=255 characters before sending
2. Reject or sanitize paste-heavy input in the search UI
3. Derive the limit from a shared constant if you control both sides

Example fix

// before
const members = await searchMembers({ workspaceId, query: rawInput });
// after
const query = rawInput.trim().slice(0, 255);
if (!query) return { members: [], memberCount: 0 };
const members = await searchMembers({ workspaceId, query });

const MEMBERS_QUERY_MAX = 255;

export function sanitizeMemberQuery(raw: string): string | null {
  const q = raw.trim().slice(0, MEMBERS_QUERY_MAX);
  return q.length > 0 ? q : null; // null → skip the search call
}

const q = sanitizeMemberQuery(userInput);
if (q) {
  const res = await searchMembers({ workspaceId, query: q });
}

function isQueryTooLong(e: unknown): e is { code: 'query_too_long'; max: number } {
  return typeof e === 'object' && e !== null && (e as any).code === 'query_too_long';
}

try {
  return await searchMembers({ workspaceId, query });
} catch (e) {
  if (isQueryTooLong(e)) {
    return searchMembers({ workspaceId, query: query.slice(0, e.max) }); // self-correct once
  }
  throw e;
}

When it happens

Trigger: Realtime/GraphQL workspace members search invoked with query.length > 255 — pasted blobs of text, generated e2e strings, or filters concatenated programmatically into the query field.

Common situations: Search box receiving a huge paste; automated tests feeding unbounded strings; client filters built by joining many terms into one query.
