Using StaticArrays with EnsembleAnalysis on ODEProblem raises LoadError (setindex!)

[gjgress]

Describe the bug 🐞

When calling componentwise_vectors_timepoint on an Ensemble Solution of an ODEProblem, if the timepoints provided are given as a SVector, it raises a LoadError due to attempting to use setindex! on the SVector.

Expected behavior

componentwise_vectors_timepoint should return the interpolated solution, as an SVector. Note that this is the behavior that occurs if the Ensemble is from an SDEProblem.

Minimal Reproducible Example 👇

using StaticArrays
using DifferentialEquations
using DifferentialEquations.EnsembleAnalysis

SDEprob = SDEProblem((u, p, t) -> 1.01u, (u, p, t) -> 1.01u, 0.5, (0.0, 1.0))
SDEensemble_prob = EnsembleProblem(SDEprob)

prob = ODEProblem((u, p, t) -> 1.01u, 0.5, (0.0, 1.0))
ensemble_prob = EnsembleProblem(prob)

SDEysim = solve(SDEensemble_prob, SOSRI(), trajectories = 1)
ysim = solve(ensemble_prob, Tsit5(), trajectories = 1)

t = SVector{11}(0:0.1:1) # t values we want to interpolate to, converted to SVector

componentwise_vectors_timepoint(SDEysim, t)[1] # Returns the interpolated u as an SVector

componentwise_vectors_timepoint(ysim, t)[1] # MethodError due to using setindex! on t

Error & Stacktrace ⚠️

The SDE timepoint interpolation returns the following:

t: 11-element SVector{11, Float64} with indices SOneTo(11):
 0.0
 0.1
 0.2
 0.3
 0.4

The error that results from the ODE interpolation is the following:

ERROR: LoadError: setindex!(::SVector{11, Float64}, value, ::Int) is not defined.
