Unable to upload file from blob storage link--Assistant api v2

I am using node js for assistants api v2.

The below code works if file is locally stored.

    const fileData = await openai.files.create({
      file: fs.createReadStream(local_file_path.pdf),
      purpose: "assistants",

but, in production file are stored in blob storage.

    const fileData = await openai.files.create({
      file: axios.get(blob_file_url, { responseType: 'stream' }),
      purpose: "assistants",

This gives me error in assistants api v2

When I used axios for assistants api v1 it worked.

The error is as follows
