This video demonstrates how to resolve the CloudFront error 'No Access-Control-Allow-Origin header'. Rishu explains three key steps: ensuring the CloudFront Distribution's Cache Behavior allows the OPTIONS method for HTTP requests, configuring CloudFront to forward appropriate CORS headers to the origin, and verifying that the origin returns the 'Access-Control-Allow-Origin' header. The tutorial provides practical guidance for developers dealing with CORS issues in CloudFront distributions.
