A media company has a static web application that is generated programmatically. The company has a build pipeline that generates HTML content that is uploaded to an Amazon S3 bucket served by Amazon CloudFront. The build pipeline runs inside a Build Account. The S3 bucket and CloudFront distribution are in a Distribution Account. The build pipeline uploads the files to Amazon S3 using an IAM role in the Build Account. The S3 bucket has a bucket policy that only allows CloudFront to read objects using an origin access identity (OAI). During testing all attempts to access the application using the CloudFront URL result in an HTTP 403 Access Denied response. What should a solutions architect suggest to the company to allow access the objects in Amazon S3 through CloudFront?
