HarmonyOS 二进制数据Uint8Array写入文件并进行解压操作报错？

Question

使用zlib.decompressFile api进行解压操作，一直报错900002 传入的目标文件错误

读取服务端加密数据进行本地解密并进行解压缩操作，一直在解压环节报错文件路径问题

代码：

let filePath = MMKVUtil.filePath+'/dataCache';
fs.mkdir(filePath).then(() => {
  console.info("mkdir succeed");

  let inputFilePath = filePath+'/data.zip';
  let file = fs.openSync(inputFilePath, fs.OpenMode.CREATE | fs.OpenMode.READ_WRITE);
  fs.writeSync(file.fd,outPutData.buffer);
  fs.closeSync(file);

  let res = fs.accessSync(inputFilePath);
  if (res) {
    console.info("file exists");
  } else {
    console.info("file not exists");
  }

  let outFilePath = filePath+'/data.json';
  let file2 = fs.openSync(outFilePath, fs.OpenMode.CREATE | fs.OpenMode.READ_WRITE);
  fs.closeSync(file2);

  let res2 = fs.accessSync(outFilePath);
  if (res2) {
    console.info("file exists");
  } else {
    console.info("file not exists");
  }

  try {
    zlib.decompressFile(inputFilePath, outFilePath, (errData: BusinessError) => {
      if (errData !== null) {
        console.error(`decompressFile failed. code is ${errData.code}, message is ${errData.message}`);
      }
    })
  } catch(errData) {
    console.error(`decompressFile failed. code is ${errData.code}, message is ${errData.message}`);
  }

}).catch((err: BusinessError) => {
  console.error("mkdir failed with error message: " + err.message + ", error code: " + err.code);
});

zlib.decompressFile的第二个参数指定的解压后的文件夹路径，提供的代码片段let outFilePath = filePath+’/data.json’;

outFile为一个文件路径，可以尝试将其修改为文件夹路径可解决900002的报错
