Neutron Hyper-V agent Exception: too many values to unpack (expected 2)

Hi, I'm using Victoria to configure OpenStack. The KVM node is working fine, but the Hyper-V node has an error and is stuck. **OpenStack Version: Victoria** **Compute Node OS Version : Windows Server 2019 Datacenter Edition** **Neutron Hyper-V agent configuration** **The following error message log will be output and the Neutron Port will be in the Building state.** 2021-06-14 07:57:19.402 6652 DEBUG neutron.agent.securitygroups_rpc [-] Update port filter for 7ae8fafd-1372-40f7-a4a0-a1f03da8cbac _apply_port_filter C:\Program Files\Cloudbase Solutions\OpenStack\Nova\Python\lib\site-packages\neutron\agent\securitygroups_rpc.py:166 2021-06-14 07:57:19.402 6652 INFO networking_hyperv.neutron.security_groups_driver [-] Updating port rules. 2021-06-14 07:57:19.402 6652 INFO networking_hyperv.neutron.security_groups_driver [-] Device 7ae8fafd-1372-40f7-a4a0-a1f03da8cbac not yet added.
