Greetings. I have a custom object workflow that will enroll on a property being known. My end goal with the workflow is to use an email property on the custom object, locate a contact, and add that contact to a static list.

My code (python 3.9) works for the search, and can return the ID just fine. When I add an import for the v3 lists endpoint

`from hubspot.crm.lists import MembershipChangeRequest, ApiException`

I receive the following lambda\_warning.

`Unable to import module 'hubspotHandler': cannot import name 'lists' from 'hubspot.crm' (/opt/python/hubspot/crm/ __init__.py)`

The private app in use has the scopes for crm.lists.read and crm.lists.write. Is this just not implimented in workflow custom code.

@Hkrewson - when I ran up against such version issues (likely cause for a new API) with HubSpot libraries in the past, I simply dropped down to the use of Python requests() functionality, constructing the URLs using basic code. I haven’t looked back since then, and do all my work at this basic call/response level. It also turns out to be easier to debug in many instances with fewer layers to interpret.

`response = requests.request("GET", propery_query_url, headers=headers)`

Best of luck!
