Issue with doca-flow sample on connectx-8

Hi,
I’m encountering an issue when attempting to run doca_flow_ct_udp sample. I have tried to use different port but got same results. The followings are the logs and all configures. What am I missing?

I’d appreciate any help.

logs:

After I switch nic to eswitch mode using sudo devlink dev eswitch set pci/0000:98:00.0 mode switchdev, the error changed.
