Variable error when retrieving node details

nicola_mendella — Wed, 04 Jun 2025 10:44:41 GMT

Code:

from netapp_ontap.resources import Node
resource = Node(uuid=uuid)
return resource.get().http_response.json()

returns:

File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/netapp_ontap/resources/node.py", line 617, in get
return super()._get(**kwargs)
File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/netapp_ontap/utils.py", line 79, in wrapper
response = func(*args, **kwargs)
File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/netapp_ontap/resource.py", line 823, in _get
self._clone_from_dict(response.json())

Thanks you,

still i don´t understand how to apply the following solution to my function:

 Exclude the "node.service_processor.ipv6_interface.netmask" field from your 
 netapp_ontap package request.

I would change your code this way:

from netapp_ontap.resources import Node resource = Node(uuid=uuid) return resource.get(fields="!service_processor.ipv6_interface.netmask").to_dict()
