Getting *** TypeError: expected string or bytes-like object on the link_token_create function call

[neerajshivam23]

For this request body I am getting type error, any luck where I may be doing wrong, curl is working as expected only on SDK call it fails.

 request = LinkTokenCreateRequest(
            products=[Products("auth")],
            client_name="Test",
            language="en",
            country_codes=[CountryCode("US")],  # type: ignore
            user=LinkTokenCreateRequestUser(client_user_id=str(user_id)), )

configuration = plaid.Configuration(
        host=get_plaid_api_host(),
        api_key={
            "clientId": config.settings.plaid_client_id,
            "secret": config.settings.plaid_secret,
            "plaidVersion": "2020-09-14",
        },
    )
api_client = plaid.ApiClient(configuration)
client = plaid_api.PlaidApi(api_client)
client.link_token_create(request)
    
  # Error:
  # *** TypeError: expected string or bytes-like object
