Module not found: Can't resolve 'fs' in 'node_modules/@aws-sdk/lib-storage/dist/es'

Describe the bug

Trying to upload a big file using multipart upload. From my React App, I'm using the method Upload from the @aws-sdk/lib-storage@3.8.1 but I'm getting this error:

node_modules/@aws-sdk/lib-storage/dist/es/bytelength.js
Module not found: Can't resolve 'fs' in '/node_modules/@aws-sdk/lib-storage/dist/es'

Your environment

SDK version number

@aws-sdk/client-s3@3.8.1
@aws-sdk/lib-storage@3.8.1

Is the issue in the browser/Node.js/ReactNative?

Node.js

Details of the browser/Node.js/ReactNative version

Node Version: 12.16.3

Steps to reproduce

let credentials = await Auth.currentCredentials();
let paralellUploadS3 = new Upload({
  client: new S3Client({
    apiVersion: '2012-08-10',
    credentials: Auth.essentialCredentials(credentials),
    region: "ca-cenral-1"
  }),
  params: {
    Bucket: 'example-bucket-s3',
    Key: 'key-file.zip',
    Body: myBody
  }
});

An issue was already open but it has been closed without fixing it. Reference to #1688 (comment)

I can confirm, I'm having the same issue on a React App I'm working on.

Running into the same issue on browser as well. I found downgrading to @aws-sdk/lib-storage@3.7.0 generates a warning instead on missing fs module.

Looking at this right now! I agree this is not ideal at all. We shouldn't even be generating that warning

[nighttiger1990]

same issue! error occurs instead of warning
SDK version number
@aws-sdk/client-s3@3.9.0
@aws-sdk/lib-storage@3.9.0
