Describe the bug

I am trying to upload a blob to the blob storage. As I am trying to get the progress while uploading the blob I use the uploadStream method like so:

const blockBlobClient = sourceClient.getBlockBlobClient(blobName);
const blockSize = 4 * 1024 * 1024; // the block size in the uploaded block blob
const uploadBlobResponse = await blockBlobClient.uploadStream(file, blockSize, 20, {onProgress: (ev) => console.log(ev)});

But as soon as the upload gets to the last line of code I get this error:

TypeError: scheduler.do is not a function at BlockBlobClient.uploadStream (Clients.js:1954)

To Reproduce
Steps to reproduce the behavior:

1. Create a new blob service client using a sas token
2. Select a file via browser select window
3. Get the container to upload the file
4. Try to upload the file using fileStream

Expected behavior
File should be uploaded without issue reporting back the progress.
