Failing to upload using `uploadStreamToBlockBlob`

I think I might've figured it out. Make sure that your stream is an actual Readable stream. That was my problem at least. Once I created a stream using `var stream = require('stream'), and then passed that stream onto the function, it worked. I followed this SO post to get help with creating a proper stream: https://stackoverflow.com/questions/48534404/create-readstream-from-base64-encoded-string-by-file

I am facing the same exact issue. Has anybody found a solution to this?

Yes, please make sure the stream is a valid Node.js Readable stream.

Thanks for the tip, that helped me identify the issue and fix some other related issues.

For me const { stream, filename, mimetype, encoding } = await file; only returns { filename: 'profilepic.jpeg' }, so the stream is null. But I'm not sure why the stream is null but the filename isn't. I am trying to investigate now but may still need help. I will post more info here if I find something out or post what was wrong if I figure it out

On the frontend, using apollo-client, I am attempting to use an upload mutation. I am passing a Blob object as the file variable. I was able to write this Blob object to my local filesystem using FileReader, and it looked visually correct, so I'm unsure what is causing the stream to be undefined on the backend.

Frontend Blob object:

Frontend mutation code:

    const src = gql`
      mutation uploadAvatar($file: Upload!) {
        uploadAvatar(file: $file) {
          filename
        }
      }
    `;

    const response = await mutate(src, { file: cropBlob }, apolloClient);

Backend mutation schema:

uploadAvatar(file: Upload!): File!

Will close this issue as this is not a SDK issue, it sounds like a logical error needs your detailed investigation, sorry I cannot give more suggestions about this. Fell free to re-open if you have further questions about SDK.
