Document Intelligence Custom Template AKS deployment and access to trained models

Question

I am following this documentation to deploy an custom document intelligence container to AKS.

https://learn.microsoft.com/en-us/azure/ai-services/document-intelligence/containers/install-run?view=doc-intel-4.0.0&tabs=custom

I deployed the custom template image, layout image, and Nginx as the reverse proxy.

I didn't deploy the document intelligence studio image as per the example because our team has already trained some models using the Azure Document Intelligence Studio and wants to reuse those Model Ids.

Both the document intelligence studio and custom container share the same subscription, endpoint, and keys.

But when I try to list the model using /form recognizer/documentModels, it does not list any models.

What am I missing here? how the containerized custom template api's have access to the models?

Note that in the logs I can see some errors like

`formrecognizercustomsupervised[0] SubscriptionId could not be found.`

and

`Failed to retrieve entry names: formrecognizer using prefix subscriptions/default/models/`
