"onUploadProgress" not working

Hi, i am trying to track the progress of file upload with the onUploadProgress function but its not working
```jsconst uploadFile = async (fileObject, res, date) => {
const bufferStream = new stream.PassThrough();
bufferStream.end(fileObject.buffer);
const Filename = `${fileObject.fieldname + "_" + date + "_" + fileObject.originalname}`;

const fileSize = fileObject.buffer.length;

const media = {
mimeType: fileObject.mimeType,
body: bufferStream,
};

const fileMetadata = {
name: Filename,
parents: ['1HuCYguIQhi0OFcnhbcr2JwPwJzsVeWzJ'],
};

const upload = drive.files.create(
{
resource: fileMetadata,
media: media,
fields: 'id,name',
},
{
onUploadProgress: evt => {
const progress = (evt.bytesRead / fileSize) * 100;
readline.clearLine(process.stdout, 0);
readline.cursorTo(process.stdout, 0);
process.stdout.write(`${Math.round(progress)}% complete`);
},
}
);
try {
const response = await upload;
console.log('File uploaded successfully');
res.status(200).send(`${Filename}`);
} catch (error) {
console.error('Error uploading file:', error);
res.status(500).send('Error uploading file');
}
};
```
i found the official example for this but even that doesn't work
https://github.com/googleapis/google-api-nodejs-client/blob/main/samples/drive/upload.js

Issue: It returns the progress only when it reaches 100%

Beginne damit, die referenzierte Datei samples/drive/upload.js zu lesen und deren Verwendung von onUploadProgress mit dem bereitgestellten Aufruf drive.files.create zu vergleichen. Reproduziere einen Upload, der Zwischenereignisse ausgeben sollte; fertig bedeutet, dass Fortschritts-Callbacks beobachtet werden, bevor der Upload 100 % erreicht.
