Procesing Lidar sensor with simulink and script

Hello, i am working to get the simulation data of Lidar Sensor in 2D provided by matlab, I am using the data of the sensor to train an algorithm of autonomous navigation, but when include the code for get the cartesian poinst of the lidar sensor in an environment, it a fail. The picture shows what tipeof error is. I am calling the script as a function with extrinsic code. To get the point only in Script it function normally but when i call as a fucntion in simulink it gives this error.
