CGIR assertion 'The type must be user provided' failed

Hello

I am getting following error when I try to build my model in Matlab R2017b for RTI1007 platform. Our previous model version was okay, Also, I can run our current model as a simulation. I guess some changes between two models are not compatible with RTI1007 but models are huge, so I need to know what type of blocks may cause this error to narrow my search.

Thank you in advance
