HarmonyOS 遇到JSON.stringify crash

function getObjectHashCode(obj: object): number { 
  const str = JSON.stringify(obj); 
  let hash = 0; 
  for (let i = 0; i < str.length; i++) { 
    const character = str.charCodeAt(i); 
    hash = (hash << 5) - hash + character; 
    hash |= 0; // 将hash转换为32位整数 
  } 
  return hash; 
}
