Issue while trying to upload file to S3 using http.put - file-upload

Question

I am trying to upload file to S3 directly from client. Here is my code to upload:
var s3Options={
"params":{
"key":options.folder+'/'+recordId+extn,
'AWSAccessKeyId':policy.s3Key,
'acl':'private',
'policy':policy.s3PolicyBase64,
'signature':policy.s3Signature,
'Content-Type':fileData.type,
'Content-Length': fileData.size,
'file':fileData,
"enctype":"multipart/form-data",
}
}
Now I am trying to upload a image and file gets uploaded but instead of image, the content-type in request is binary/octet-stream and when I access the file in app, it shows me message in console:
Resource interpreted as Image but transferred with MIME type binary/octet-stream:
Here is how I am uploading the file:
HTTP.put('https://'+process.env.S3_BUCKET+'.s3.amazonaws.com/'+options.folder+'/'+recordId+extn ,s3Options,function(error,result){
console.log("put file", error, result)
}
Now lets say my file's url is https://myBucket.s3.amazonaws.com/User/avatar/profile.png. Here is the content of file:
This is the put request sent to upload the file:
