I\'m following the instructions from this answer to generate the follow S3 bucket policy:
{
\"Id\": \"Policy1495981680273\",
\"Version\": \"2012-10-17\",
\
From IAM docs, http://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements.html#Action
Some services do not let you specify actions for individual resources; instead, any actions that you list in the Action or NotAction element apply to all resources in that service. In these cases, you use the wildcard * in the Resource element.
With this information, resource should have a value like below:
"Resource": "arn:aws:s3:::surplace-audio/*"
