This test worked by accident in the past. The parser threw an error here, not because of the query syntax error, but because of an internal error in the parser that crashed parsing.

const typeErrorCausingQuery = 'from []';

const { result } = renderHook(() => useEsqlIndex(typeErrorCausingQuery, 'esql'));
