HarmonyOS使用HashMap崩溃

//遍历map集合，并且生成一个Record对象（对应JAVA中JSONObject,可转换成类似于JSON串或者JSON对象的操作） 
mapIterator(map:HashMap<string, string|number>){ 
  let record:Record<string,string|number> = {}; 
  try { 
    let iter = map.keys(); 
    let temp: IteratorResult<string> = iter.next(); 
    while(!temp.done) { 
      let key = temp.value; 
      let value = map.get(key); 
      if(value){//简单判空。可不要 
        record[key] = value 
      } 
      temp = iter.next(); 
    } 
  }catch (err){ 
    console.log(err); 
  } 
  return record; 
}
