Failed to run DOCA DPA app and samples

Hi, I failed to run DOCA DPA samples(dpa_initiator_target and dpa_ping_pong) and DPA All-to-all application in DOCA 2.9.0 or 2.9.1LTS. The samples throw errors like:

sudo ./doca_dpa_ping_pong -pf_dev mlx5_0 -rdma_dev mlx5_2

And the dpa all-to-all application threw the following error:

[08:12:56:474454][513852][DOCA][ERR][doca_sync_event.cpp:651][initialize_dpa] Sync_event 0xaaab04264e80: Failed to initialize dpa. can't create dpa sync_event with an extended dpa context

The samples and application work fine in DOCA 2.7 or DOCA 2.8, but doesn’t work when I upgrade DOCA to 2.9 or 2.9.1LTS by reinstalling the BF bundle.
What is the cause of these problems and what should I do to solve them?

Thanks!
