This is because the decay eta' -> rho0 + gamma has no model included, one can see this in the printout:

2. eta' --> rho0 + photon
Interaction model(s):
[eta'_fixed_g_rho0] Fixed product masses {/}
[eta'_genbod_g_rho0] Pluto build-in genbod {/genbod}

I don't know if this is the correct physics model, but a decay with a simple Breit-Wigner can done by adding these lines:

PHadronDecayM1N *newmodel =
new PHadronDecayM1N("rho_model@eta'_to_rho0_g", "Patched rho model", -1);
makeDistributionManager()->Add(newmodel);
