Why am I receiving syntax errors for a file that I know can compile fine?

I received this error when running my MatLab model that uses C-caller functions. I know that this code works and it compiles in VSCode. I am fairly certain that it's because of MatLab configurations but I am very much brand new with MatLabs so I would not know where to look for in the settings. I do have the model configurations to link to the right custom code. I have tried playing with the spacing in the header file and tried changing the language to C++ like how the error suggested.

You could try using

typedef struct SOMENAMEGOESHERE {
...
} FUNCTION_1_REQUEST_T;

instead of

typedef struct {
...
} FUNCTION_1_REQUEST_T;

I did try that and it gives me the same error
