User: "My Lambda function keeps getting 403 AccessDenied when reading from bucket 'my-app-data'. I added this bucket policy:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": "*",
            "Action": "s3:GetObject",
            "Resource": "arn:aws:s3:::my-app-data/*"
        }
    ]
}

But it still doesn't work. What am I doing wrong? Should I also disable Block Public Access?"
