It is a common error and currently the error that you get does not mention the real issue.

Why can't we retrieve the ROBOT_DOF from the length of the wbi_id_list?

The thing is that ROBOT_DOF and wbi_id_list live in two different worlds. ROBOT_DOF (which was meant to be temporary) is used only in the Matlab workspace to initialize certain variables while wbi_id_list is only parsed within the blocks in the "C++ world". The solution would be having the Matlab parser that I'm currently using also counting the number of DOF. Gimme a couple of hours and I will come back with a solution.

Any solution for providing a clear error message? @jeljaik @francesco-romano I think that for non-expert users, it's not easy to recognize the dimension mismatch between the length of wbi_id_list and the variable ROBOT_DOF immediately
