Okay I’ll need an issue on SciMLSensitivity.jl and I’ll need some time to dive into this one.
Ok, I think it is related to the update_coefficients of a ScalarOperator, where it is trying to change the value of a Float64 ScalarOperator into a Dual one. Do you want I make the issue on SciMLSensitivity.jl?
