It seems you are using an old version of FractionalDiffEq.jl, the latest release of FractionalDiffEq.jl working fine

Oh, I see, the examples are not updated timely, maybe try out the latest API? convert all the FODESystem to FODEProblem, we are trying to standardize all the APIs to the SciML standards.

Thanks it worked
