Error: IntervalNonlinearProblem has no field u0

[nathanrboyer]

Describe the example

I am trying to solve a series of simple IntervalNonlinearProblems where the parameters change. This used to work, but I cannot seem to get back to an environment where it works now. I followed the tutorials and got an implementation working previously, but that same code no longer works even if I pin SimpleNonlinearSolve to an older version. 😕

Minimal Reproducible Example 👇

Unable to change the parameters of the problem with remake.
I don't remember the output from IntervalNonlinearProblem about uType being there before; that seems weird.

using SimpleNonlinearSolve
f(u, p) = u * u - 2.0 + p[1]
uspan = (1.0, 2.0)
prob_int = IntervalNonlinearProblem(f, uspan)  # "IntervalNonlinearProblem with uType nothing. In-place: false"
problem = remake(prob_int, p=[0])  # error here
solution = solve(problem)  # didn't make it this far

Working Environment (please complete the following information):

I can't find one that works, but everything was working fine on the latest versions about 6 months ago. It must be a dependency that changed.

Additional context

Actual code:

function find_proportional_limit(table::DataFrame, searchrange::Tuple=(1e1, 1e6))
    @assert(
        (length(searchrange) == 2) && (typeof(first(searchrange)) == typeof(last(searchrange))),
        "`searchrange` must be a `Tuple{T,T} where T<:Number` (two elements of the same type)"
    )
    σ_p = Float64[]
    problem = IntervalNonlinearProblem(KM620.plasticity, searchrange)
    for row in eachrow(table)
        problem = remake(problem, p=row)
        solution = solve(problem)
        push!(σ_p, solution.u)
    end

@avik-pal do you know what happened to this default alg?

[avik-pal]

It seems to hit

SciMLBase.jl/src/problems/problem_interface.jl

Line 19 in c2fb81f

SymbolicIndexingInterface.state_values(prob::AbstractSciMLProblem) = prob.u0

, which probably needs to be caught earlier because unlike other SciMLProblems it does have a u0.

Probably @AayushSabharwal would know how to handle this?
