Review comment:
Add these code after creating 'PreparedContext' function:
`
} catch (NoSuchElementException noElementException) {
borrowPrepareContext = false;
preparedContext =
createPreparedContext(sqlRequest.getProject(), sqlRequest.getSql());
preparedContext.olapRel =
QueryContextFacade.current().getOlapRel();
preparedContext.resultType =
(QueryContextFacade.current().getResultType());
}
`
