A google search for this exception doesn't turn up anything interesting. I suspect I mis-configured things, although I'm not sure. Could someone point me in the right direction? Thank you for your time and consideration.

I'm using Amazon IAM for the particular key ID and access key and just bumped into the same 403 Forbidden... Turns out you need to give permissions that target both the bucket root and its subobjects:

{
  "Statement": [
    {
      "Principal": {
          "AWS": "*"
      },
      "Effect": "Allow",
      "Action": "s3:*",
      "Resource": ["arn:aws:s3:::bucket-name/*", "arn:aws:s3:::bucket-name"]
    }
  ]
}
