Uploading to aws s3 with chunkMode: false fails.

When Trying to upload a file to aws s3 with the next options:

chunkedMode: false,
httpMethod: 'PUT',
headers:

{ 'Content-Type' : 'image/jpg' }

the response from amazon is:

Message>A header you provided implies functionality that is not implemented</Message><Header>Transfer-Encoding</Header>

It seems that Transfer-Encoding header is being sent thus s3 fail.
