Error message

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

What it means

Thrown when searching workspace members with a query longer than 255 characters. The hard cap is fixed at 255 in the realtime member-search resolver.

Solutions

1. Limit the search input to 255 characters on the client (maxLength=255).
2. Trim/truncate the query before sending.
3. Validate length before calling the resolver.

Example fix

// before
<input onChange={e => search(e.target.value)} />
// after
<input maxLength={255} onChange={e => search(e.target.value.trim().slice(0, 255))} />

const QUERY_MAX = 255
function safeQuery(q: string) {
  return q.trim().slice(0, QUERY_MAX)
}

function isValidMemberQuery(q: string): boolean { return q.trim().length <= 255 }

try { await searchMembers(ws, q) } catch (e) {
  if (e.code === 'query_too_long') searchMembers(ws, q.slice(0, 255))
  else throw e
}

When it happens

Trigger: Calling the workspace member search with input.query.length > 255 (e.g. pasting a very long string, a search box without maxlength).

Common situations: No client-side maxlength on the search input; pasting a document by accident; programmatic search with unbounded input.
