I3C Target always Nack

Hello,I'm a newbie ,and I'm facing some issues..

I used two NUCLEO-H503RB boards, one as a controller and the other as a target. I connected them as shown below.

And I tried them  with the Example code "I3C_Controller_Private_Command_IT & I3C_Target_Private_Command_IT",but the target always responds with a NACK.

I have tried changing the frequencies for both open-drain and push-pull modes, but the problem persists.

Could you advise on how to resolve this issue? Also, is my wiring correct? I noticed in the PDF that an interface board is plugged into the NUCLEO-H503RB. Could this be causing the issue? If so, is there an alternative board I can use instead of the X-NUCLEO-IKS01A3, since it seems it's no longer available?
