azure.core.exceptions.HttpResponseError: Operation returned an invalid status 'Forbidden'

I ran into a problem which involves obtaining data from my Azure digital Twin using the python script in Blender. I am currently trying to obtain some temperature value from one of my iot devices and retrieve it in my blender application and get it to show in the software. Thus, what I have here is my ADT_ENDPOINT_URI (my digital twin host name or the Azure digital twin explorer website), then I created an application in App registration for Blender, and got my tenant_ID, Client_ID, and also the client secret value. I set all of the above as my credential for the script to have access. Meanwhile, in the role assignment, I have the following roles: Azure Digital Twin data, Contributor, Owner, and App Configuration Data. Then I ran the script, and the console shows the error message: azure.core.exceptions.HttpResponseError: Operation returned an invalid status 'Forbidden'

However, before the error, I also have: INFO:azure.identity._internal.get_token_mixin:ClientSecretCredential.get_token succeeded. Now after this, I have INFO:azure.core.pipeline.policies.http_logging_policy:Response status: 403, which occurred after the message: A body is sent with the request, in which the request headers are as follow: 'Content_type', 'Content- Length', 'Accept':'application/json', request id and user-agent. The Authorization is shown as 'REDACTED'. What could be the cause of this error.

    Hi @Juanhe Shen Thank you for posting the question on this forum. Have you looked into the code sample from Python SDK The sample provides a reference on how to get the Digital Twin data using Python. I have tried the same code and could extract a single property of the Digital Twin. Please refer the below code sample change I have added to the GitHub code to extract a single property from the returned Digital Twin dictionary.

    import os
    import sys
    import logging
    from azure.identity import DefaultAzureCredential
    from azure.core.exceptions import HttpResponseError
    from azure.digitaltwins.core import DigitalTwinsClient
        url = os.getenv("AZURE_URL")
        # DefaultAzureCredential expects the following three environment variables:
        # - AZURE_TENANT_ID: The tenant ID in Azure Active Directory
        # - AZURE_CLIENT_ID: The application (client) ID registered in the AAD tenant
        # - AZURE_CLIENT_SECRET: The client secret for the registered application
        credential = DefaultAzureCredential()
        # Create logger
        logger = logging.getLogger('azure')
        handler = logging.StreamHandler(stream=sys.stdout)
        # Create service client and enable logging for all operations
        service_client = DigitalTwinsClient("https://<ADTInstanceName>", credential)
        digital_twint_id = "ReadingTank"
        # Get twin
        digital_twin = service_client.get_digital_twin(digital_twint_id)
        print("Starting to print digital twin")
        print('Extracting level of material')
        for key, value in digital_twin.items():
            if key == 'Level_of_Material':
    except HttpResponseError as e:
        print("\nThis sample has caught an error. {0}".format(e.message))

    For testing purposes I have directly provided the ADT instance URL in the line of the code where the service_client is initialized. I have also removed the function overload logging_enable=True. I could get the twin data as expected and could extract the value. Please refer the below image for reference.
