Describe the bug 🐞
Hi,
I am trying to optimize a Split ODE with a NN embedded. While I can run the inference, the optimization w/ Zygote throws an UndefRefError. I am not sure if this is the right place to a bug report or if the bug is rather in Zygote. Since the same optimization works fine with an ODEProblem, I suspect that it is not Zygote though.

Expected behavior
Not throw an error ;)

Minimal Reproducible Example 👇

using Flux, Optimization, OrdinaryDiffEq, OptimizationOptimisers, SciMLSensitivity

##
N = 2^2
data   = randn(Float32, 3, 100, N)
u0 = repeat(Float32[0, 0, 1], 1, N)

##
ann = Chain(Dense(3, 50, tanh), Dense(50, 3))
pann, st = Flux.destructure(ann)
train_loader = Flux.Data.DataLoader((data, u0); batchsize=N)

##
const H1 = Float32[ 0 0 1; 0 0 0; -1 0 0]
function dudt_rot(u, pann, t)
    return H1 * u
end
function dudt_relax(u, pann, t)
    return st(pann)(u)
end

##
function predict_neuralode(pann, u0)
    sol1 = solve(
        SplitODEProblem{false}(
            SplitFunction{false}(
                ODEFunction{false}(dudt_rot),
                ODEFunction{false}(dudt_relax),
            ), u0, (0f0, 1f0)),
            Rosenbrock23(), p = pann, saveat = collect(range(0f0, 1f0, 100)))
    return permutedims(Array(sol1), (1, 3, 2))
end
predict_neuralode(pann, u0)

##
function loss_neuralode(pann, data, u0)
    pred = predict_neuralode(pann, u0)
    loss = sum(abs2, data .- pred)
    return loss, pred
end
loss_neuralode(pann, data, u0)

##
optf = Optimization.OptimizationFunction((pann, pnothing, data, u0) -> loss_neuralode(pann, data, u0), Optimization.AutoZygote())
optprob = Optimization.OptimizationProblem(optf, pann)
result_neuralode = Optimization.solve(optprob, OptimizationOptimisers.Adam(0.001), train_loader)
