Erdős-Hajnal bound for the three-edge hypergraph on four vertices

Let $K_4^{(3)-}$ be the three-uniform hypergraph with three of the four possible edges on four vertices. Every $K_4^{(3)-}$-free three-uniform hypergraph on $N$ vertices has an independent set of size at leastEquivalently, $r(K_4^{(3)-},K_k^{(3)})\le k^{Ck}$.
