Document Intelligence Custom Template AKS deployment and access to trained models

Silas, Sajan 0

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/`

Hi @Silas, Sajan,

Thank you for reaching out to Microsoft Q&A forum!

The issue you're encountering seems related to authentication and container configuration. The error messages indicate that the custom container is unable to authenticate with Azure Document Intelligence. Since you're not using Document Intelligence Studio, ensure that the container has the correct API key, endpoint, and subscription ID set in its environment variables.

Additionally, verify that the container can access the Azure resource where the models are stored and that the required permissions are in place. Check the .env file to ensure that the necessary credentials are correctly configured. If the problem persists, review your Azure subscription’s access permissions and API authentication setup.

Thank you.

Hello, Thanks for the response. I was able to fix the error by creating a config map as suggested in this post https://learn.microsoft.com/en-us/answers/questions/1342098/form-recognizer-container-custom-template-3-0-fail
{ "version": 1, "collections": { "formrecognizer": {} } }

Now the API is returning the pre-built models but the custom models are still not returning.

I have verified the billing endpoint and API key used in the environment variables and they are all looking good. I think the container will run only if these values are setup correctly.

You have mentioned subscription id, but I cannot find any env variable to pass that in the documentation.
