[Pulp-list] Pulp 3.3 error on listing publications

[Bin Li (BLOOMBERG/ 120 PARK)]

Hi All
Listing publications gives the following error when any publication is being created. I don't recall see this issue before 3.3. Can this be fixed?

Traceback (most recent call last):

ValueError: Invalid value for `metadata_checksum_type` (), must be one of ['unknown', 'md5', 'sha1', 'sha224', 'sha256', 'sha384', 'sha512']


To reproduce the issue. run the below program when a creating publication task is running.

#!/usr/bin/env python
from pulpcore.client import pulpcore
from pulpcore.client import pulp_rpm
from pulpcore.client.pulp_rpm import PublicationsRpmApi

# Configure HTTP basic authorization: basic
configuration = pulpcore.Configuration()
configuration.host = 'http://pulpserver'
configuration.username = 'admin'
configuration.password = 'admin'
configuration.safe_chars_for_path_param = '/'

rpm_client = pulp_rpm.ApiClient(configuration)

PublicationsRpmApi(rpm_client).list().results
