The ArgumentError that is thrown is:

ERROR: LoadError: ArgumentError: Bridge of type `MathOptInterface.Bridges.Constraint.ScalarFunctionizeBridge{Float64, MathOptInterface.EqualTo{Float64}}` does not support setting the attribute `MathOptInterface.Test.UnknownConstraintAttribute()` because `MOIB.Constraint.invariant_under_function_conversion(MathOptInterface.Test.UnknownConstraintAttribute())` returns `false`.

Reproducible example:

julia> using MathOptInterface; const MOI = MathOptInterface
MathOptInterface

julia> inner = MOI.Utilities.Model{Float64}();

julia> model = MOI.Bridges.Constraint.ScalarFunctionize{Float64}(inner);

julia> MOI.Test.test_model_copy_to_UnsupportedAttribute(model, MOI.Test.Config())
