Cannot deserialize input data due to invalid discriminator value.

[Christophoclese]

Hi, I am getting an ApiValueError when attempting to retrieve a list of our server assets. I'm not sure if this is something I'm doing wrong. This is using version 1.0.11.9235 of the module.

Code:

from intersight.api import view_api

api_instance = view_api.ViewApi(api_client)
api_response = api_instance.get_view_server_list(top=1)

Traceback:

Traceback (most recent call last):

Sorry for the slow response on this issue. While waiting on a fix an alternative to the view_api using the compute_api can be found at https://github.com/dsoper2/DEVWKS-2254/blob/main/src/clive_intersight_python.ipynb:
import intersight.api.compute_api

Create physical summary (server) class instance

api_instance = intersight.api.compute_api.ComputeApi(api_client)

Find the count of servers in the account

server_query = api_instance.get_compute_physical_summary_list(count=True)
print(server_query)

Intersight limits the number of items returned. Page through returned results and select Name, Model, Serial

per_page = 50
query_select = "Name,Model,Serial"
for i in range(0, server_query.count, per_page):
page_query = api_instance.get_compute_physical_summary_list(top=per_page, skip=i, select=query_select)
print(page_query)

Thanks for the suggestions @dsoper2!

I ended up implementing an alternate workaround by passing _preload_content=False into get_view_server_list(). This disables the automatic serialization of JSON into objects.

import intersight

from intersight.api import view_api

page_size = 100
page_start = 0
server_list = []
records_available = 0

# Initialize the View API client
view_api_instance = view_api.ViewApi(self.intersight_client)

# Attempt to obtain information on servers in Intersight
while page_start <= records_available:
    api_response = view_api_instance.get_view_server_list(
        _preload_content=False,
        top=page_size,
        skip=page_start,
    )
    intersight_data = json.loads(api_response.read())
    server_list += intersight_data['Results']
    page_start += page_size
    records_available = intersight_data['Count']
