CNAMEAlreadyExists

Question

I am trying to associate a CNAME record in my route53 hosted zone to a CloudFront distribution and am seeing this error message:  
  
com.amazonaws.services.cloudfront.model.CNAMEAlreadyExistsException: One or more of the CNAMEs you provided are already associated with a different resource. (Service: AmazonCloudFront; Status Code: 409; Error Code: CNAMEAlreadyExists; Request ID: 3349d478-c36e-45aa-a658-8e0b7ef76d01; Proxy: null)  
  
I have no other cloudfront distributions. Please advise.  
  
Thanks

Answer

This has to do with attempting to use an S3 & Cloudfront deployment after using the amplify console kept failing at the build stage. Using python > 3.7 in lambdas caused a backend build error which was resolved using:   
  
https://github.com/aws-amplify/amplify-console/issues/595#issuecomment-761049327  
  
Erasing the S3 Cloudfront instances and erasing the custom domain from wihtin the amplify console then re-configuring it sorted out all the issues.  
  
The confusing part was an error message referencing the domain being associated with another cloudfront distribution when there was no other cloudfront distribution.
