server-client-python: 400011: Bad Request when publishing .hyper datasource

After reviewing issue #488 , I found that I am experiencing the issue on single table extracts as opposed to multi.

any help and suggestions would be appreciated. I have tried several variations in specifying file paths and publish modes but all fail with a bad request.

Thanks!

Here is my code

import tableauserverclient as TSC
import os

cwd = os.getcwd()
file = 'Groups.hyper'

tableau_auth = TSC.TableauAuth(username,password)
server = TSC.Server('http://'+server_name)
server.use_server_version()
server.add_http_options({'verify': False})

with server.auth.sign_in(tableau_auth):
    new_datasource = TSC.DatasourceItem(project_id, 'Groups Extract python')
    new_datasource = server.datasources.publish(new_datasource,
    os.path.join(cwd,file),
    'CreateNew')

Running with error
