s3 client.uploadFile() hangs with no error - node.js

Question

My credentials work successfully with AWS cli to upload s3 files, the credentials are associated with an admin user on a bucket which is a static site. Update: Download works as expected. For some reason the node 's3' package fails, but no error is displayed, it just logs:
progress 0 4561 4561
progress 0 4561 4561
...
unable to upload: RequestTimeout: Your socket connection to the server was not read from or written to within the timeout period. Idle connections will be closed.
at Request.extractError (/Users/../node_modules/aws-sdk/lib/services/s3.js:700:35)
at Request.callListeners (/Users/../node_modules/aws-sdk/lib/sequential_executor.js:106:20)
at Request.emit (/Users/../node_modules/aws-sdk/lib/sequential_executor.js:78:10)
at Request.emit (/Users/../node_modules/aws-sdk/lib/request.js:688:14)
And I'm not sure what the problem would be? Any insights? The code is below, it's taken directly from the s3 package https://www.npmjs.com/package/s3
// RUNNING NODE 11.0 (due to un-updated dependencies in s3 or aws-sdk it must be under 11.15)
const { accessKeyId, secretAccessKey } = require('./tools/AWS.json')
const s3 = require('s3')
const AWS = require('aws-sdk')
const awsS3Client = new AWS.S3({
accessKeyId,
secretAccessKey,
signatureVersion: 'v4',
region: 'us-east-2',
})
const client = s3.createClient({
s3Client: awsS3Client,
})
const liveBucket = 'my-bucket'
const params = {
localFile: 'out/404.html',
s3Params: {
Bucket: liveBucket,
Key: '404.html',
},
}
const uploader = client.uploadFile(params)
uploader.on('error', function(err) {
// never runs ...
console.error('unable to upload:', err.stack)
})
uploader.on('progress', function() {
// runs like 5 times before failing after a long wait
console.log('progress', uploader.progressMd5Amount, uploader.progressAmount, uploader.progressTotal)
})
uploader.on('end', function() {
// never runs ...
console.log('done uploading')
})

It looks like your upload hangs because of a bucket permissions issue. Please try to add the following permissions to your bucket:
s3:PutObject
s3:PutObjectTagging
s3:ListBucketMultipartUploads
s3:ListMultipartUploadParts
