Error related to pdg code when simulating decays

Hi!

I have a model in which a particle Ups4s decays into b+ b-. I am trying to simulate the decay events with an external .hepmc file:

import model modelN_UFO
import_events decay Upsilon-distr.hepmc
decay ups4s > b+ b-
add process displaced_decay ups4s
output test
launch test

The structure of the file Upsilon-distr.hepmc is as follows:
