Problem in Model predictive controller for DC-DC converter Plant model cannot be a pure direct feed-through system without additional dynamics

I am designing a model predictive controller for the DC-DC converter. I have developed a DC-DC converter in the matlab simulink. I have connected approprietly MPC controller with DC-DC converter. However, when I am designing the MPC controller in MPC desginer and using define and linearize the plant model, i am receving an error "Plant model cannot be a pure direct feed-through system without additional dynamics"
I am attaching the snapshot of my simulation and error.
I am not able to identifiy the mistake.

Hi I had the same issue. I solved specifying the proper MV and MO signals. Honestly I cannot understand if you choosed the correct signal, but I suggest to try all the signals and hope it works.
