Simulink error: Size of data type 'CAN_MESSAGE' has not been set

Hello everyone, I am working on a model using CAN bus to receive data.But when building the model it pops out an ERROR:"Size of data type 'CAN_MESSAGE' has not been set" and I can't find solution anywhere.

My environment: Matlab2018b, Visual Studio 2015, Freescale s32ds v1.0. I am coding for a VCU which contains a MPC5744 as CPU (perhaps)

And I have asked the guy from the VCU company, he said the model seems to be fine, the problem may be about my environment or something else...

Sincere appreciation for any advice!!

Hello,

Could you share you Simulink file to investigate the issue?
