Cannot solve remake problem with vector parameter of non-Real

[cstjean]

Describe the bug 🐞

prob_vec = ODEProblem(model2, u0, (0.0, 18.0), ps_vector);
prob_vec_remade = remake(prob_vec; p=ps_vector)

solve(prob_vec)         # works
solve(prob_vec_remade)  # fails, BoundsError: attempt to access 0-element Vector{Float64} at index [1]

Expected behavior

As far as I understand, remaking the problem with the same parameter vector should yield an identical/equivalent Problem.

Minimal Reproducible Example 👇

using ModelingToolkit
using ModelingToolkit: t_nounits as t, D_nounits as D
using DifferentialEquations: solve, Euler, ImplicitEuler
using SymbolicIndexingInterface,SciMLStructures
using DataInterpolations
using Symbolics
using ModelingToolkit:remake

const ConstantFun = typeof(ConstantInterpolation([10.0, 12, 13], [0, 6, 12]))
I_inputs_0 = ConstantFun[ConstantInterpolation([10.0, 12, 13, 13], [0, 6, 12, 18]),
                         ConstantInterpolation([15.0, 14, 13, 13], [0, 6, 12, 18])]

eval_interpolation(interp, t) = interp(t)
@register_symbolic eval_interpolation(interp::ConstantFun, t)

@variables I(t)[1:2] Z(t)[1:2]
@parameters I_input[1:2]::ConstantFun
eqs = [I[1] ~ eval_interpolation(I_input[1], t),
       D(Z[1]) ~ I[1],
       I[2] ~ eval_interpolation(I_input[2], t),
       D(Z[2]) ~ I[2]]

@named model = ODESystem(eqs, t)
model2 = structural_simplify(model)

u0 = [Z => [0.0011, 0.0011]]
ps_vector = [I_input => I_inputs_0]

prob_vec = ODEProblem(model2, u0, (0.0, 18.0), ps_vector);
prob_vec_remade = remake(prob_vec; p=ps_vector)

solve(prob_vec)         # works
solve(prob_vec_remade)  # fails
