Describe the bug

I am following the docs here, I hope I have not missed anything!

I have an externally-generated user pool that I need to import into my CDK app. I have this definition in my resource.ts file for the auth backend.

When I run npx ampx sandbox I get the error:

amplify/backend.ts(21,26): error TS2339: Property 'cfnResources' does not exist on type 'ReferenceAuthResources'.
TypeScript validation check failed.
Resolution: Fix the syntax and type errors in your backend definition.

Reproduction steps

My auth backend file is identical to the one in the docs, with the variables such as poolID populated.

import { referenceAuth } from '@aws-amplify/backend';

export const auth = referenceAuth({
  userPoolId: 'us-east-1_xxxx',
  identityPoolId: 'us-east-1:b57b7c3b-9c95-43e4-9266-xxxx',
  authRoleArn: 'arn:aws:iam::xxxx:role/amplify-xxxx-mai-amplifyAuthauthenticatedU-xxxx',
  unauthRoleArn: 'arn:aws:iam::xxxx:role/amplify-xxxx-mai-amplifyAuthunauthenticate-xxxx',
  userPoolClientId: 'xxxx',
});

Hey @Catazza, thank you for reaching. Tried reproducing but did not observe this error message on a sandbox deploy.
But did notice @aws-amplify/backend-cli: 1.0.4 does appear to be put of date. Could you try upgrading this to the latest(1.4.2) version and restart sandbox using --debug flag?
Additionally, on the backend.ts file is the auth resources being overridden?
