Hi Hassan Hotait, its nice to hear you have solved it.

im facing the similar issue you have posted. i made a custom message using "ros2genmsg()" and when i run the simulink model i get a error message saying

STD exception 'mwboost::wrapexcept<mwboost::exception_detail::current_exception_std_exception_wrapper<std::invalid_argument> >': 'Connection to process with Exchange: "5f1470ff-8f66-40e9-84fb-5f3bfd116a13 " was lost.' was caught.

it would be thankful of you if you can share how you made it work.
