Use private Python packages with Azure Machine Learning - PAT Auth

Question

Hi,

I am trying to deploy a model on an AKS cluster in Azure Machine Learning that uses a Python package that is present as a package in a feed on Azure DevOps.
I found the following article that explains how to do this:

https://learn.microsoft.com/en-us/azure/machine-learning/how-to-use-private-python-packages

In the example it shows that in the Worspace.set_connection method, it passes a string as "value".
If I try to do the same in my code the following error appears:

azureml._base_sdk_common.workspace.models.machine_learning_service_error.MachineLearningServiceErrorException: (ValidationError) JSON format is expected for Properties.Value

Looking at the documentation (azureml.core.workspace.workspace) it actually says that it expects a JSON:
value: the json format serialization string of the connection details)

What format and what information should this JSON contain?

Thanks,
G.

@G Cocci Thanks for the question. Please find the example for PAT passing.

from azureml.core import Workspace  
  
pat_token = input("Enter secret token")  
ws = Workspace.from_config()  
ws.set_connection(name="connection-1",   
   category = "PythonFeed",  
   target = "https://<my-org>.pkgs.visualstudio.com",   
   authType = "PAT",   
   value = “\’”+pat_token+”\’”)
