test_get_current_longview_plan is failing locally for me with the following error:

test_linode_client = <linode_api4.linode_client.LinodeClient object at 0x10554cda0>

    def test_get_current_longview_plan(test_linode_client):
        lv_plan = test_linode_client.load(LongviewPlan, "")
    
>       assert "Longview" in lv_plan.label
E       TypeError: argument of type 'NoneType' is not iterable

test/integration/models/longview/test_longview.py:58: TypeError
=========================================================================== short test summary info ===========================================================================
FAILED test/integration/models/longview/test_longview.py::test_get_current_longview_plan - TypeError: argument of type 'NoneType' is not iterable

After I changed my Longview plan from Longview Free to Longview Pro 3 pack, it passed. Is this the intended behavior?

Good catch, looks like Longview free plan actually does not return anything and update using longview_plan_update() function is not allowed. I revised the assertion so it only checks when something is returned
