### Describe the bug

In a CDK created app, when I click the button Edit `Continuous deploys set up` in any Frontend environment branch, the settings don't open and I get this error in Chrome, Chrome in Incognito mode and Firefox.

### Expected behavior

Expected to open the settings as explained in https://docs.aws.amazon.com/amplify/latest/userguide/amplify-config-autogeneration.html

What I want is to get `aws-exports.js` autogenerated and I think the guide linked is a good approach.

### Reproduction steps

1. Create AWS CDK v1.124.0 stack using `@aws-cdk/aws-amplify`
2. Deploy the CDK stack that will automatically deploy the Amplify application.
2. Follow the Amplify documentation steps https://docs.aws.amazon.com/amplify/latest/userguide/amplify-config-autogeneration.html

### Build Settings

```yaml
version: 1
applications:
- appRoot: packages/frontend
env:
variables:
AMPLIFY_DIFF_DEPLOY: true
frontend:
phases:
preBuild:
commands:
- yarn workspaces focus
build:
commands:
- yarn run build
artifacts:
baseDirectory: out
files:
- "**/*"
cache:
paths:
- "packages/frontend/.next/cache/**/*" # Cache Next.js for faster application rebuilds
- "packages/frontend/node_modules/**/*" # Cache `node_modules` for faster `npm i`
- "packages/frontend/.yarn/cache/**/*" # Cache `node_modules` for faster `yarn`
```

### Additional information

I created the Amplify app using AWS CDK and configured the branches in the CDK stack. This is the first time I want to edit those branches to disable Continuous deploys in some branches.

In my case, it only happens with Amplify applications created through AWS CDK. So far, I have used many features of Amplify for this CDK-created application without errors. Here is the code for the CDK stack.

```typescript
import * as codebuild from '@aws-cdk/aws-codebuild';
import * as amplify from '@aws-cdk/aws-amplify';
import * as cdk from '@aws-cdk/core';
import * as yaml from 'yaml';
import * as fs from 'fs';
import * as path from 'path';
import { redirects } from './amplifyRedirects';

export class MyAmplifyStack extends cdk.Stack {
constructor(scope: cdk.Construct, id: string, props?: cdk.StackProps) {
super(scope, id, props);

// The code that defines your stack goes here

// Configuration variables

const amplifyYamlPath = path.resolve(__dirname, AMPLIFY_YAML_PATH);
const amplifyYaml = yaml.parse(
fs.readFileSync(amplifyYamlPath, FILE_ENCODING),
);

const amplifyApp = new amplify.App(this, AMPLIFY_APP_NAME, {
sourceCodeProvider: new amplify.GitHubSourceCodeProvider({
owner: GITHUB_REPOSITORY_USER,
repository: GITHUB_REPOSITORY_NAME,
oauthToken: cdk.SecretValue.secretsManager(AWS_SECRET_GITHUB_OAUTH),
}),

buildSpec: codebuild.BuildSpec.fromObjectToYaml(amplifyYaml),
});

branches.forEach((branch) =>
amplifyApp.addBranch(branch, {
pullRequestPreview: false,
}),
);

redirects.forEach((redirect) =>
amplifyApp.addCustomRule({
source: redirect.source,
target: redirect.target,
status: redirect.status,
condition: redirect.condition,
}),
);
}
}

```

Start with the AWS CDK v1.124.0 reproduction and the provided TypeScript stack, then follow the Build settings flow for a CDK-created app. Use the linked aws-exports.js autogeneration guide as the expected behavior. Done means Edit opens the frontend branch settings and the configuration can be changed successfully in the reported browsers.
