azure.core.exceptions.ClientAuthenticationError: DefaultAzureCredential failed to retrieve a token from the included credentials.

Question

from azure.identity import DefaultAzureCredential

from azure.mgmt.network import NetworkManagementClient

import time

credential = DefaultAzureCredential()

network_client = NetworkManagementClient(credential, subscription_id)

network_interface = network_client.network_interfaces.get(resource_group, nic_name)

Using the above code I was trying to read network details, but I am getting the below error

File "/usr/lib/python3/dist-packages/azure/identity/_credentials/chained.py", line 111, in get_token
    raise ClientAuthenticationError(message=message)

Thank you for posting your query on Microsoft Q&A, the above shared indicates that the DefaultAzureCredential object was unable to obtain a valid authentication token from any of the available credential sources.

From above error it seems that the EnvironmentCredential object was unable to obtain a valid authentication token from the environment variables.

EnvironmentCredential: EnvironmentCredential authentication unavailable. Environment variables are not fully configured.

Kindly validate the following:

Ensure the appropriate environment variables are set prior to application startup for the intended authentication method and this has appropriate permissions assigned.

• To authenticate a service principal using a client secret, ensure the variables AZURE_CLIENT_ID, AZURE_TENANT_ID and AZURE_CLIENT_SECRET are properly set.
• To authenticate a service principal using a certificate, ensure the variables AZURE_CLIENT_ID, AZURE_TENANT_ID, AZURE_CLIENT_CERTIFICATE_PATH, and optionally AZURE_CLIENT_CERTIFICATE_PASSWORD are properly set.
• To authenticate a user using a password, ensure the variables AZURE_USERNAME and AZURE_PASSWORD are properly set

Still if this does not work then, Please install developer CLI, once installed, authenticate to your Azure account using 'azd auth login', this will get the access token from AzureDeveloperCliCredential.

Please do let me know if you have any further queries.
