We are trying to generate token for custom rest api endpoint. We are using Azure Synapse Notebook in PySpark.
from azure.identity import DefaultAzureCredential,ManagedIdentityCredential import requests credential = ManagedIdentityCredential(client_id='xxxxxx-xxxx-xxxx-xxxx-xxxxx') This code execute successfully without error. I know alternatively we can use ClientSecret authentication but because of complaince reason we have to use ManagedIdentityCredential only.
But using credential object if we try to get_token it throws error
token = credential.get_token("api://xxxxxx-xxxx-xxxx-xxxx-xxxxx/.default") ManagedIdentityCredential.get_token failed: ManagedIdentityCredential authentication unavailable, no managed identity endpoint found. --------------------------------------------------------------------------- CredentialUnavailableError Traceback (most recent call last) Cell In [9], line 1 ----> 1 token = credential.get_token("api://xxxxxx-xxxx-xxxx-xxxx-xxxxx/.default")
