s3 Bucket Policies Access Denied

Question

I am trying to upload an object on s3 from aws-sdk-js, but cannot figure out policies for my case. I want to allow only one user to have upload access and a public read access.

Here are my s3 bucket policies

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "PublicReadForGetBucketObjects",
            "Effect": "Allow",
            "Principal": {
                "AWS": "*"
            },
            "Action": "s3:GetObject",
            "Resource": "arn:aws:s3:::some-bucket/*"
        },
        {
            "Sid": "",
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::1111111111111:user/some-bucket-user"
            },
            "Action": "s3:*",
            "Resource": "arn:aws:s3:::some-bucket/*"
        }
    ]
}

And My IAM policies are :

{
  "Version":"2012-10-17",
  "Statement":[
    {
      "Sid":"AddPerm",
      "Effect":"Allow",
      "Action":"s3:*",
      "Resource":["arn:aws:s3:::some-bucket/*"]
    }
  ]
}

Can someone please point out what I am doing wrong here?

My bad, I was not initialising the AWS.S3 correctly and it was using the users/roles of the ec2 instance and not the one I was assigning.
