I am writing a CFT for a website hosted on S3 - The YML file passes template-validate with no issues however the build agent returns the following error:

yaml.constructor.ConstructorError: could not determine a constructor for the tag '!GetAtt'

Outputs:
  WebsiteURL:
    Value: !GetAtt RootBucket.WebsiteURL
    Description: URL for website hosted on S3

回答1:

Try it without the shorthand version of Fn::GetAtt

Outputs:
  WebsiteURL:
    Value: Fn::GetAtt: [ RootBucket, WebsiteURL ]
    Description: URL for website hosted on S3
