AWS Lambda function for URL masking

Question

I have a vanity URL that I want to redirect to a specific page in a website(Cloudfront Distribution). I can do a redirect with Masking from GoDaddy but it does not help me with https options for the vanity URL. So I was thinking of doing this using Lambda function triggered on Viewer Request section of the CF distribution. I am using the following code for the Lambda function, can anyone let me know what I am doing wrong as I am getting an error from CF side-

```
import json

def lambda_handler(event, context):
  request = event['Records'][0]['cf']['request']
  response = {
    'status': '301',
    'statusDescription': 'Moved Permanently',
    'headers': {
        'location': [{
            'key': 'Location',
            'value': 'https://cf-distribution/page/'
        }]
      }
   }
  return response
```

Hi Deep,

Without sharing the exact error you're getting from CloudFront it isn't easy to help you, but I  will share with you the following links that are a good reference for what you're trying to build:
* [Handling Redirects@Edge](https://aws.amazon.com/blogs/networking-and-content-delivery/handling-redirectsedge-part1/)
* [AWS CloudFront - Redirect the viewer to a new URL
](https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/example-function-redirect-url.html)

Also, it's important to remember that AWS Lambda@Edge functions must be deployed in the N. Virginia (us-east-1) region.

Let me know if that helped you and if not, please comment by adding the exact errors you mention you're getting from CloudFront so we can help you further.
