Hi @leonie25, welcome to the forum :smile:

Gurobi’s support for nonlinear constraints is a very recent feature. You need to install Gurobi v12.

You can check which version of Gurobi you are running with

import Gurobi
Gurobi._GUROBI_VERSION

We should be able to automatically install Gurobi v12, so do:

import Pkg
Pkg.update()

then restart Julia.

If that doesn’t work, please run

import Pkg
Pkg.status()

and let me know what the output is.
