Error Code: MalformedPolicy;

I have the following policy

s3Permissions:
  Type: AWS::S3::BucketPolicy
  Properties:
    Bucket: ${self:provider.environment.S3_BUCKET}
    PolicyDocument:
      Id: Policy1590589947784
      Version: '2012-10-17'
      Statement:
      - Sid: getObjectFromS3
        Action:
        - s3:GetObject
        Effect: Allow
        Resource: arn:aws:s3:::${self:provider.environment.S3_BUCKET}
        Principal: "*"

I keep getting the following error when I try to deploy

An error occurred: s3Permissions - Action does not apply to any resource(s) in statement (Service: Amazon S3; Status Code: 400; Error Code: MalformedPolicy; Request ID: 3760256F6D1080A1; S3 Extended Request ID: B5vLNJkgcg1+i0///DAY/jgXDgejJgUaXbKSIA3uBfdq5KJMEeD9nLPlJWgOYZPYKTwhKdPQees=).

How do I correctly set the bucket policy?

bad indent I suppose!
