400 ERROR: The request could not be satisfied

Question

I am deploying the system on cloudfront services,
When I type Url: domain.com/%d it shows "400 ERROR" page. I want it to return to index.html page when the link is wrong. I don't know if this is a Bug or a feature.
Example: Link: https://booking.com/%d

Answer

I think that CloudFront considers this as an invalid HTTP request because %D doesn't correspond to any URL encoded ASCII character.

Answer

Hi,

If I understood you correctly, you are looking at how to customize error processing in CloudFront. Please take a look [here](https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/GeneratingCustomErrorResponses.html) - there are examples of how you can achieve what you want.
