I've imported from a serverless project this restApi.

const restApiId = cdk.Fn.importValue(envRelated(`ApiGateway-restApiId`));
const rootResourceId = cdk.Fn.importValue(envRelated(`ApiGateway-rootResourceId`));
this.apiGw = apigateway.RestApi.fromRestApiAttributes(this, envRelated(`apigw`), {
	restApiId: restApiId,
	rootResourceId: rootResourceId,
});

When deploying with cdk deploy, all resources are updated but not the stage.
No deployment is created.
I've tried also to force a deployment with this snippet.

new Deployment(this,envRelated('deployment-stage') , {
      api: apiGw
    });

Salting the deployment id makes no difference.
After the deployment is done, the api gateway is still pointing to the previous deployment instead of the new deployment done.

Specifying the stage with the forced deployment fails because stage already exists.
