Cannot simulate FMU Import from Simulink

Hello everyone,

For the past few days, I've been attempting to export an FMU from Simulink, but I've been encountering issues (I have attached the model below). I have followed all the steps outlined in the documentation here, but it seems like I might be overlooking something. I have used a simple Simulink adder as my Simulink model (refer to the image). When I try to import it as a Simulink model, the simulation works fine. However, when I try to import the same Simulink model as an FMU, even after using Sim Configuration in Cameo, it doesn't work. Can someone help me understand what I might be missing? I am using Cameo version 2022X.
