A three-body force acting between the η -meson and two nucleons was overlooked inadvertently in the model description and discussion in the published version of our paper “Onset of η -nuclear binding in a pionless EFT approach” [Phys. Lett. B 771 (2017) 297–302] while present in the actual numerical calculations. The stated conclusion that a stabilizing ηNN contact term was not needed is therefore incorrect. Such a three-body force, associated with a new low energy constant dηNNΛ , must be introduced at leading order to stabilize η -nucleus systems.
