amazon s3 - S3 Invalid Resource in bucket policy

Question

I'm trying to make my entire S3 bucket public, but when I try to add the policy:

{
  "Id": "Policy1454540872039",
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "Stmt1454540868094",
      "Action": [
        "s3:GetObject"
      ],
      "Effect": "Allow",
      "Resource": "arn:aws:s3:::sneakysnap/*",
      "Principal": {
      "AWS": [
         "985506495298"
    ]
  }
  }
  ]
}

It tells me that my "Resource is invalid", but that is definitely the right arn and that is definitely the right bucket name. Anyone know what's going on?

Answer 1

I had this "problem" when I was trying to set a policy on the wrong bucket. That is, my arn in the policy was reading arn:aws:s3:::my-bucket-A/* but I was attempting to set it on my-bucket-B
