Just one question about quadratic term in the multi-objective optimization. As it is mentioned in [this post](https://discourse.julialang.org/t/jump-constrain-with-quadratic-equation/91432/4) “HiGHS supports quadratic objectives”, but I got `BoundsError: attempt to access 0-element Vector{MultiObjectiveAlgorithms.SolutionPoint} at index [1] ` for this type of objectives in the multi-objective mode! Can you explain the reason?
