Set related to the queryBuilder suddenly stopped working

am trying to retrieve data with relational retrieval.
var whereClause=“objectId= '” + object.objectId + " ’ ";
var queryB = Backendless.DataQueryBuilder.create().setWhereClause(whereClause);
queryB.setRelated([“columnNameA”, “columnNameB”]);
var object = await Backendless.Data.of(“tableName”).find(queryB);

I checked there’s relation value with columnNameA and columnNameB .

Hello @adel_kasno

....setWhereClause(whereClause);

Is whereClause definite?

yes, I’ve edited the question.

SOLVED:
in the user security role, the loadRelations permission was denied, I just allowed it.
Thanks
