Redirect a hosted domain to another is failing

I would not do this with an object in a bucket. You can do this far more efficiently with a Lambda@Edge Function in a CloudFront distribution. To do this you would use a single CloudFront distribution. You can configure by default up 100 alternate domain names fo r a CloudFront distribtion.

Place a Lambda@Edge function on your distribution that redirects based on the host-header that it receives.

As an example:

function handler(event) {
    var request = event.request;
    var requestHeaders = request.headers;
    console.log("Request: " + JSON.stringify(request) + ".");

    // The new URL in the new site.
    var newurl = 'butterflies-child-care.click' 
   
  var response301 = {
        statusCode: 301,
        statusDescription: 'Moved Permanently',
        headers: {
            'location': { value: newurl },
            'cache-control' : { value: 'max-age=31536000, immutable' },
            'strict-transport-security' : { value: 'max-age=31536000; includeSubDomains' }
        }
    };

    if ( requestHeaders['host'].value !== newurl){
        console.log("Response: " + JSON.stringify(response301) + ".");
        return response301
    }

    // Default 
    return response;
}

This function will return a 301 to newurl, when presented with any request where the host header is not newurl.

Please test and ensure this code works, I wrote this without testing it in CloudFront - may have syntax and logic errors!
