cdk deploy error with amplify exported backend (appsync + auth)

I have and amplify app that has an API Graphql and Auth. Both created from amplify cli. I then exported the amplify app using
`amplify export --out ` following this [guide](https://docs.amplify.aws/javascript/tools/cli/usage/export-to-cdk/#pageMain)

I then proceeded to add in into a CDK project to deploy it on another account and region following this [guide](https://docs.amplify.aws/javascript/tools/cli/usage/export-to-cdk/#use-cdk-for-cross-account-or-cross-region-amplify-backend-deployments)

```typescript
const amplifyBackend = new AmplifyExportedBackend(this, "amplifyExportedBackend", {
amplifyEnvironment: `dev-${cdk.Stack.of(this).region + cdk.Stack.of(this).account}`,
path: path.resolve('.', 'amplify-export-amplifyapp')
})
```

After running deploy I am getting this error:

Expected Behavior
stack should be deployed in the account and region

This works if I remove the auth, export the amplify app again and only deploy the api.

Node version: v20.10.0
Amplify CLI version: 12.10.1

Comienza con la invocación de AmplifyExportedBackend y el backend exportado que utiliza el despliegue de CDK. Inspecciona cómo se proporcionan los parámetros authRoleName y unauthRoleName cuando API y Auth se exportan conjuntamente, y compáralo con la exportación API-only que tiene éxito. La tarea estará completada cuando el backend exportado se despliegue correctamente en la cuenta y región de destino con Auth habilitado.
