I was wondering whether there exist bugs of calling for "value(function, expr) ". My codes are like this:

M = Model()

@variable(M, x)

@variable(M, y)

@NLconstraint(M, con, x + x*y^2 - 3 >= 0)

t = all_constraints(M; include_variable_in_set_constraints = true)

D = Dict(x => 1)

value(x β get(D,x,x), t[1])

An error is thrown that
