[Python] Extracting credentials from 1Password using onepassword python library

I am using this python library ("OnePassword python client") in which to interact with my 1Password instance and extract API credentials from a vault named "Employee".

Python Function:

def authenticate(base_endpoint, api_key, api_secret):
op = OnePassword()
available_vaults = op.list_vaults()
employee_vault = next((vault for vault in available_vaults if vault["name"] == "Employee"), None)
if not employee_vault:
print("No Employee vault found")
items = op.list_items(vault=employee_vault["id"])
addepar_item = next((item for item in items if item["title"] == "Addepar API"), None)
if not addepar_item:
print("Please check that Addepar API item exists in 1Password")
item_details = op.get_item(uuid=addepar_item["id"], fields=["username", "credential"])
if not item_details:
print("Please check that Addepar API item credentials exists in 1Password")
api_key = item_details["username"]
api_secret = item_details["credential"]
base_endpoint = "https://myfirm.addepar.com/api/v1/"


This function works flawlessly on a Mac, however, PC users are getting the following error:

PC User error:

onepassword.MissingCredentials

My Thoughts: I have unsuccessfully attempted to contact the developer to understand what onepassword.MissingCredentials might be refering to, however, I wonder if anyone else has come across this error before, and if so, the troubleshooting steps to resolve?
