errors occurring when implementing ALO based FOPID controller code in a simulation using MATLAB function block

I am using Ant-Lion Optimization (ALO) to improve the performance of FOPID controllers in a microgrid simulation. While implementing the ALO code along with FOPID in simulation, I am getting some errors like "Errors occurred during parsing of MATLAB function", "Function call failed" and so on. Code itself does not have any errors but they occur only when combining with simulation. What could be the solution for this?

I am using FOMCON and Ant-Lion Optimizer toolboxes.
