MissingParameter: Parameter 'inputTreeNamesg' not found

[fojensen]

Following the instructions in the "Anti-jet discriminator" section of the README.me file:
https://github.com/greyxray/TauAnalysisTools/blob/CMSSW_10_4_0_pre3_tau-pog_RunIIAutumn18MiniAOD/README.md

I issue the following command in Step 5:
python TauAnalysisTools/test/runTauIdMVATrainingMiniAOD_deltaBeta_dR05.py
and issue the make command as printed to the screen.

Which leads to an error
<reweightTreeTauIdMVA>: terminate called after throwing an instance of 'edm::Exception' what(): An exception of category 'Configuration' occurred. Exception Message: MissingParameter: Parameter 'inputTreeNamesg' not found.

I see the parameters are attempting to be loaded here:
https://github.com/greyxray/TauAnalysisTools/blob/CMSSW_10_4_0_pre3_tau-pog_RunIIAutumn18MiniAOD/TauAnalysisTools/bin/reweightTreeTauIdMVA.cc#L173-#L174

Which pulls from the following template cfg, where I see inputTreeNamesg is absent:
https://github.com/greyxray/TauAnalysisTools/blob/CMSSW_10_4_0_pre3_tau-pog_RunIIAutumn18MiniAOD/TauAnalysisTools/test/reweightTreeTauIdMVA_cfg.py#L20-L56

Perhaps it would be safer to check for the parameter before attempting to fetch it?
Instead of setting the parameters as is shown here:
https://github.com/greyxray/TauAnalysisTools/blob/CMSSW_10_4_0_pre3_tau-pog_RunIIAutumn18MiniAOD/TauAnalysisTools/bin/reweightTreeTauIdMVA.cc#L173-#L176
instead make an explicit check if the parameter is there. For example,

std::string inputTreeNamesg, inputTreeNamebg; if (cfgReweightTreeTauIdMVA.existsAs<std::string>("inputTreeNamesg")) { inputTreeNamesg = cfgReweightTreeTauIdMVA.getParameter<std::string>("inputTreeNamesg"); } else { inputTreeNamesg = inputTreeName; } if (cfgReweightTreeTauIdMVA.existsAs<std::string>("inputTreeNamebg")) { inputTreeNamebg = cfgReweightTreeTauIdMVA.getParameter<std::string>("inputTreeNamebg"); } } else { inputTreeNamebg = inputTreeName; }
