我想在上传时分析图像，如果内容被认为是不合适的，则对其进行模糊处理。
日志this image is inappropriate工作正常，所以检测工作正常。但是我没有看到之后的任何日志，所以我猜blurImage函数不能正常工作。
我很难调试这个函数中的错误，以及为什么我看不到任何进一步的日志。

exports.controlImage = functions.storage.object().onFinalize(
  async (object) => {
    const bucket = storage.bucket(object.bucket);
    const file = bucket.file(object.name);

    const fileName = object.name;
    const destBucket = admin.storage().bucket(bucket);
    const file = destBucket.file(filePath); */
    

    
  
    // Check the image content using the Cloud Vision API.
    return client.safeSearchDetection(`gs://${bucket.name}/${file.name}`)
    .then((data) => {
      const safeSearch = data[0];
      functions.logger.log('SafeSearch results on image', safeSearch);
  
      if (safeSearch.safeSearchAnnotation.violence === 'VERY_LIKELY' ||
          safeSearch.safeSearchAnnotation.violence === 'POSSIBLE' ||
          safeSearch.safeSearchAnnotation.adult === 'VERY_LIKELY' ||
          safeSearch.safeSearchAnnotation.adult === 'POSSIBLE') {
            functions.logger.log("this image is innapropriate")
            blurImage(object.name, object.bucket, object.metadata);
            return null
      }
      else functions.logger.log("this image is ok")
      return null;
    });
}
)

  const tempLocalFile = path.join(os.tmpdir(), filePath);
