HarmonyOS 鸿蒙Next 回调方法里面无法获取到回调回来的数据

export class CallQueryData {
err?: BusinessError<void>;
resultSet?: relationalStore.ResultSet

constructor(resultSet?: relationalStore.ResultSet, err?: BusinessError<void>) {
this.err = err;
this.resultSet = resultSet;
}
}
//接口定义
export interface QueryCallback {
call(query: CallQueryData): void
}
///方法实现
//根据谓词指定的查询条件查找数据
public getData(serviceId: string, userId: string, tableName: string, atomArr: string[], whereMap: Map<string, ValueType>, call: QueryCallback) {
let predicates = new relationalStore.RdbPredicates(tableName);
whereMap.forEach((value, key) => {
predicates.equalTo(key, value); // 匹配表tableName中key为val的字段
});
if (store != undefined) {
(store as relationalStore.RdbStore).query(predicates, atomArr, (err: BusinessError<void>, resultSet: relationalStore.ResultSet) => {
if(call) {
let queryD = new CallQueryData(resultSet, err)
call.call(queryD)
}
if (err) {
console.error(Failed to query data. Code:<span class="hljs-subst">${err.code}</span>, message:<span class="hljs-subst">${err.message}</span>);
// reject(err);
return;
}
console.info(ResultSet column names: <span class="hljs-subst">${resultSet.columnNames}</span>, column count: <span class="hljs-subst">${resultSet.columnCount}</span>);
})
} else {
if(call) call.call(new CallQueryData(undefined, new CommonDBError(‘数据库未初始化。’)))
}
}
///方法调用
this.mDBUtil.getData(serviceId, userId, this.CONVERSATION_TABLE.tableName, this.CONVERSATION_TABLE.columns,
whereMap, (queryD: CallQueryData) => {
console.info("添加数据返回信息==== " + queryD.err + " ====== " + queryD.resultSet);
if (queryD.resultSet) {
let infoS = this.valuesBucket2ConversationInfo(queryD.resultSet);
if(call) call.call(infoS, undefined)
} else {
if(call) call.call(undefined, queryD.err)
}
})
调用方法返回回来的queryD是undefined， 断点调试显示的queryD对象是有值的， 回调回来就是undefined
请帮忙确认已下具体原因， 我这个是跨lib访问方法会有影响吗？ 回调方法里面无法获取到回调回来的数据。
