  We study a general metric constrained interpolation problem in a de
Branges-Rovnyak space $\mathcal{H}(K_S)$ associated with a contractive
multiplier $S$ between two Fock spaces along with its commutative counterpart,
a de Branges-Rovnyak space associated with a Schur multiplier on the
Drury-Arveson space of the unit ball of $\mathbb{C}^n$.
