root domain does not redirect to subdomain in amplify

Question

I own the domain `derbyware.com` in `Route 53`, I deployed a static website with amplify.
I want the website to be served on `nidam.derbyware.com` which works
derbyware.com to always redirect to nidam.derbyware.com so that only that the subdomain serve the website.
right now derbyware.com also serve the website, it does **NOT** redirect to nidam. subdomain.

![config](/media/postImages/original/IMwEpQvRnVRLS0viaRtYxeqw)

as you can see in the image the root domain is set to serve the branch staging, which is the only branch there is.
so after searching I found that I should add this rule in redirects. I'l taking about the first rule, the second one is there by default

```
[
  {
    "source": "https://derbyware.com",
    "status": "302",
    "target": "https://nidam.derbyware.com"
  },
  {
    "source": "/<*>",
    "status": "404-200",
    "target": "/index.html"
  }
]
```
but it still does not work.

Note the that when I login and go to https://us-east-1.console.aws.amazon.com/amplify/apps/d1rnle5j0ejefa/domains I see this error message that says "The role with name AWSAmplifyDomainRole-Z32DQIOI2NLNAJ cannot be found." in case that's related.

how can i have have derbyware.com redirect to nidam.derbyware.com. Thanks.

Can you try this redirect URL. ``` [ { "source": "https://derbyware.com/<*>", "target": "https://nidam.derbyware.com/<*>", "status": "301" } ] ```

Based on your issue, there are a few things to check to get your root domain redirection working properly in AWS Amplify:

1. First, make sure both your root domain (derbyware.com) and subdomain (nidam.derbyware.com) are added in the Amplify domain management. This is a common oversight - you need to include both domains in Amplify's domain settings for the redirection to work properly.

2. For the redirect configuration, your rule looks close but might need adjustment. Try this format instead:
```
{
"source": "/",
"status": "302",
"target": "https://nidam.derbyware.com"
}
```

3. In your Route 53 configuration, ensure you have:
- A CNAME record for "nidam.derbyware.com" pointing to your Amplify app
- An A record alias for "derbyware.com" pointing to your Amplify app

4. The error message about "AWSAmplifyDomainRole" could be related to permissions issues. This role is used by Amplify for domain management. You might need to recreate this role or check IAM permissions.

5. In the Amplify console under domain settings, make sure you've selected the option "Setup redirect from https://derbyware.com to https://nidam.derbyware.com".

If the issue persists after these changes, try removing both domains from Amplify and adding them again, making sure to include both the root domain and subdomain in the process.

can you verify in Amplify Console → Hosting → Custom domains that:

- Both derbyware.com and nidam.derbyware.com are listed
- Their status shows as "Available"
- SSL certificates are properly provisioned

Also change the redirect rule

```
[
  {
    "source": "https://derbyware.com",
    "status": "301",
    "target": "https://nidam.derbyware.com"
  },
  {
    "source": "https://www.derbyware.com", 
    "status": "301",
    "target": "https://nidam.derbyware.com"
  },
  {
    "source": "/<*>",
    "status": "404-200",
    "target": "/index.html"
  }
]
```
301 is for Permanent Redirect
