            - /*
  Bucket: !Ref MyWebsite

I receive the error message above when I deploy my bucket policy.

When I use the yaml lint site it says format is fine but when I use the CLI sam validate --lint command I get this message:

>/Users/travissalmon/Desktop/Web Development/Resume Challenge/cloud-resume-challenge/template.yaml is a valid SAM Template

Not sure what to do.

I tried this template and it worked with no issues for me.

sam validate: success

sam deploy -g: success

This is the script I used.
