AttributeError: 'PipelineResponse' object has no attribute 'get'

[SiberianTiger01]

hello Azure SDK for Python team,

my client set up Pacemaker on SUSE Linux Enterprise Server in Azure, came across the Error "ERROR: Failed: Unable to deserialize to object: type, AttributeError: 'PipelineResponse' object has no attribute 'get'". As a Azure support engineer, I have tried many times but failed to fix this error. As I traced the origin of PipelineResponse class, https://docs.microsoft.com/en-us/python/api/azure-core/azure.core.pipeline.pipelinerequest?view=azure-python, I found PipelineResponse class is one part of Azure SDK for Python.
Accordingly, I am asking for help from the team which is the contributor for PipelineResponse class. I need some documentation about PipelineResponse class which I cannot find online. Also, May I have some debugging hints about this error.

Thank you very much for your help

Thanks @SiberianTiger01
We will need a bit more information in order to get find the best people to help - the PipelineResponse object is a structural part of all the Azure Python SDKs, so it would be great if we could narrow this down a bit.
Are you able to provide a more complete error stack so we can see which file/SDK is raising the attribute error?
Or maybe your client is able to provide more details as to which Azure services they are using?
In order to help diagnose this, we will need to figure out details such as which Azure SDK is being used, which version is installed, and which APIs are being used.

You can find more information on the PipelineResponse, and how it fits into the SDK pipeline here:

the hosting vm is Azure VM using SLES 15 image. Python2.7.18 and Python 3.6.15 are installed.
Client set up STONITH by using an Azure fence agent following this article: https://docs.microsoft.com/en-us/azure/virtual-machines/workloads/sap/high-availability-guide-suse-pacemaker
Client install the Azure fence agent and other dependency packages by zypper install.

vm-psapapp04:/home/azureuser # rpm -qa |grep fence-agents
fence-agents-4.9.0+git.1624456340.8d746be9-150100.7.32.1.x86_64

After installation, client tried to start the service rsc_st_azure by below command:

fence_azure_arm -l 'ceb2620c-xxxx-xxxx' -p '9C58QV7VELveaxxxxx' --resourceGroup 'RG-LPMAUSAPPROD-AE-APP-01' --subscriptionId 'xxx-xxx' --tenantId 'xxxx-xxx-xxx' -o list -v

but failed to kickstart the service, and error pop out:
ERROR: Failed: Unable to deserialize to object: type, AttributeError: 'PipelineResponse' object has no attribute 'get'

attached detailed snippets of /var/log/messages file

The STONITH device uses a service principal to authorize against Microsoft Azure. Client use an Azure fence agent, which restarts a failed node via the Azure APIs.

Thanks @SiberianTiger01
From the linked guide - the only reference I can find to the Python SDK is here in step 10A, which would seem to narrow the scope down to either azure-identity or azure-mgmt-compute.

# You might need to activate the public cloud extension first. In this example, the SUSEConnect command is for SLES 15 SP1
 SUSEConnect -p sle-module-public-cloud/15.1/x86_64
 sudo zypper install python3-azure-mgmt-compute
 sudo zypper install python3-azure-identity

However from this alone it's still hard to tell where the error is occurring.
Could you let us know whether the client is installing to Python 2 or Python 3? (Python 2 is no longer officially supported by the Azure SDK).
Additionally, which versions of these Python packages are being installed?
Do we know how these packages are being consumed?

This could be an issue in the framework/agent that's calling into the SDK, rather than the SDK itself. It could also be worth reaching out to the authors of the guide to see if they can provide more details.

Thanks - I'll tentatively tag this as identity for now.

From the log, I found:
ClientSecretCredential.get_token succeeded -- looks like we got the access token successfully.

@msyyc can you take a look?

[SiberianTiger01]

yes, CX login successfully. but came across this error, "ERROR: Failed: Unable to deserialize to object: type, AttributeError: 'PipelineResponse' object has no attribute 'get'"

Hi @SiberianTiger01, thanks for your feedback, I used the same package version, but did not reproduce your results.

Could you please run the following demo script and tell us your results?

import os
import sys
import logging

from azure.identity import DefaultAzureCredential
from azure.mgmt.compute import ComputeManagementClient

logger = logging.getLogger('')
logger.setLevel(logging.DEBUG)
handler = logging.StreamHandler(stream=sys.stdout, )
logger.addHandler(handler)
formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
handler.setFormatter(formatter)

credential = DefaultAzureCredential()
SUBSCRIPTION_ID = os.environ.get("AZURE_SUBSCRIPTION_ID", None)

compute_client = ComputeManagementClient(credential, SUBSCRIPTION_ID, api_version='2020-06-01')

resource_group_name = 'your-resource-group-name'    # replace this
for res in compute_client.virtual_machines.list(resource_group_name):
    print(res)
