Is `cloudasset.googleapis.com/v1p4beta1` deprecated?

[AkselAllas]

I got 404 for the following request following readme step python bfs.py --org_id <orgId> --source <serviceAccountEmail>

(line 59 in bfs.py)

        res = requests.post("https://cloudasset.googleapis.com/v1p4beta1/organizations/{}:analyzeIamPolicy".format(org), headers=headers, json=JSON_REQUEST)

I get 400 if I change v1p4beta1 to v1 but then it says parent is not a valid field.
