When creating or running a model using the MATLAB And SImulink Robotics toolbox, I get the following error:
Error evaluating 'InitFcn' callback of block_diagram 'untitled'. Callback string is 'RPInit'
Caused by:
  • Changing property 'UnconnectedLineMsg' is not allowed

To fix the error, go to the Simulink model settings and set the UnconnectedLineMsg connectivity diagnostic to 'none'. See how to do it in the picture below:
