Undefined function 'getNumInputs' for input arguments of type 'struct'

Hello, I was working with Simulink to build a battery electric vehicle & i m getting this error when I run. I am not sure what 'getNumInputs' mean. Someone please help me.

Can you share your model and the exact error message that you are receiving?

I am getting the same error: Undefined function 'getNumInputs' for input arguments of type 'struct'

and: Undefined function 'getRawData' for input arguments of type 'struct'

I found out these came from copy and pasting code and something did not paste right
