estoy tratando de programar un ejercicio no lineal pero me sale el siguiente error

LoadError: The solver does not support an objective function of type MathOptInterface.ScalarQuadraticFunction{Float64}.

Puedes dar un ejemplo que causa el error?

este es el codigo que hice

```julia
m=Model(with_optimizer(Cbc.Optimizer))

# variables 
@variable(m, x >= 0)
@variable(m, y >= 0)
@variable(m, z >= 0)

# restricciones
@constraint(m, x>=50)
@constraint(m, x-50+y>=50)
@constraint(m, x+y-100+z>=50)

# funcion objetivo

@objective(m, Min, x^2+y^2+z^2+12(x-50)+12(x+y-50))

`optimize!(m)`
# valor de la funcion objetivo
F = x^2+y^2+z^2+12(x-50)+12(x+y-50)
#imprimimos los resultados 
println("El valor de la variable x es:", JuMP.value(x))
println("El valor de la variable y es:", JuMP.value(y))
println("El valor de la variable z es:", JuMP.value(z))
println("El valor optimo de nuestro sistema es:", JuMP.value(F))`Preformatted text`

```

Parece que te faltar llamar a `optimize!(m)`, puesto que lo tienes en “backticks”
