julia> using ForwardDiff, Optimization
julia> Optimization.OptimizationFunction((x,p) -> x^2, Optimization.AutoForwardDiff())
(::OptimizationFunction{true, AutoForwardDiff{nothing, Nothing}, var"#3#4", Nothing, Nothing, Nothing, Nothing, Nothing, Nothing, Nothing, Nothing, Nothing, Nothing, Nothing, typeof(SciMLBase.DEFAULT_OBSERVED_NO_TIME), Nothing, Nothing, Nothing, Nothing, Nothing, Nothing, Nothing, Nothing, Nothing}) (generic function with 1 method)
Can you check if the SciMLBase being used in your case, maybe from the base environment is very old, that seems most likely?
So it would seem: SciMLBase v1.81.0.
Since I have the same versions for Optimization.jl and ForwardDiff.jl, compat seems incorrect.
