Problem with Pythia8 output

Asked by MoritzHuck

Hi,

I'm trying to plug a new model with Feynrules/Madgraph5/Pythia8. Everything is ok until I want to make an output for pythia8 . The model uses 2 Fermion to 2 (Scalar/Fermion/Verctor) interactions in a 4 particle vertex.

The first message occurs when I try a e+ e- > s1+ s1- (Scalars) process:

Command "output pythia8" interrupted with error:
AttributeError : 'NoneType' object has no attribute 'get'
Please report this bug on https://bugs.launchpad.net/madgraph5
More information is found in 'MG5_debug'.
Please attach this file to your report.

The second message occurs when I try a e+ e- > e+ e- Process (as test):

Command "output pythia8" interrupted with error:
KeyError : ('FFSS1', 4)
Please report this bug on https://bugs.launchpad.net/madgraph5
More information is found in 'MG5_debug'.
Please attach this file to your report.

For the second there was a bug #861263, which is marked as solved. So I am nor sure if this is a question or a bug.

The Debug for the first is:
