GCP Cloud Storage 上传文件 SaveOptions onUploadProgress 只回调一次

Question

I am trying to get the progress when I upload file to GCP cloud storage by Node.js. I found there is an onUploadProgress in SaveOptions, but this is only callback one time.

        storage.bucket(bucket_name).file(file_path).save(buffers, {
                onUploadProgress: (progressEvent) => {
                    console.log(progressEvent)
                }
            }
        )

And the progressEvent value is like below, and bytesWritten's value is the file size.

{ bytesWritten: 80248835, contentLength: '*' }

Is it possible to get the realtime upload progress event from Node.js client library? (@google-cloud/storage)

Thank you.

I can received many times callback after I add chunkSize.

const chunkSize = 8 * 1024 * 1024;
storage.bucket(bucket_name).file(file_path).save(buffers, { chunkSize: chunkSize,
        onUploadProgress: (progressEvent) => {
            console.log(progressEvent)
        }
    }
)
