Bug in OptimizationMOI when using HiGHS.Optimizer() but works with Ipopt.Optimizer()

[avinashresearch1]

Describe the bug 🐞

bug in:

Optimization.jl/lib/OptimizationMOI/src/moi.jl

Line 19 in ccc63d2

if f.adtype isa Optimization.AutoModelingToolkit

ERROR: TypeError: in isa, expected Type, got a value of type typeof(AutoModelingToolkit)
Stacktrace:
 [1] OptimizationMOI.MOIOptimizationCache(prob::OptimizationProblem{…}, opt::MathOptInterface.OptimizerWithAttributes; kwargs::@Kwargs{…})

Minimal Reproducible Example 👇

using Optimization, OptimizationMOI, Ipopt


obj_f(x, p) = 12*x[1] + 20*x[2]
x0 = zeros(2)
_p = SciMLBase.NullParameters()
cons = (res, x, p) -> res .= [
    6*x[1] + 8*x[2]
    7*x[1] + 12*x[2]
    ]
    
opt_fun = OptimizationFunction(obj_f, Optimization.AutoModelingToolkit(); cons = cons)
prob = OptimizationProblem(opt_fun, x0, _p; lcons = [100.0, 120.0], ucons = [+Inf, + Inf], lb = [0.0, 0.0], ub = [+Inf, 3.0])
    

res = solve(prob, Ipopt.Optimizer()) # WORKS

using HiGHS
res = solve(prob, HiGHS.Optimizer()) # ERROR
 
res = solve(prob, OptimizationMOI.MOI.OptimizerWithAttributes(HiGHS.Optimizer)) # SAME ERROR
