I am getting an error code that I don't know how to decode

ROOT Version: ROOT 6.30/02
Platform: Lxplus
Compiler: Python


My code crashes when computing the histograms for dijet mass, I am unable to understand what the error is even telling me which makes this a hard problem to solve. The code it uses is

ComputeInvariantMass_code = 
ROOT::VecOps::RVec<double> ComputeInvariantMass(ROOT::VecOps::RVec<float> pt, ROOT::VecOps::RVec<float> eta, ROOT::VecOps::RVec<float> phi,
 ROOT::VecOps::RVec<float> m)
{
  if(2 > pt.size()) return ROOT::VecOps::RVec<double> {std::numeric_limits<double>::min()};
  
  TLorentzVector p[2];
  //This creates all the p vectors
  for(int i ; i < pt.size(); i++) p[i].SetPtEtaPhiM(pt[i], eta[i], phi[i], m[i]);

  //We create an empty RVec
  ROOT::VecOps::RVec<double> r;
  //Then create an RVec with all possible unique 2 combinations of indexes for the momentum vectors
  auto v_1 = ROOT::VecOps::Combinations (pt, 2);
  //We then define a size to make the r RVec accomidate all the combinations 
  const auto size = v_1[0].size();
  r.reserve(size);

  //We then fill up the r RVec with index values from v_1 for the momentum then get invariant mass
   for(int i=0; i<size; i++) {
      r.emplace_back((p[v_1[0][i]] + p[v_1[1][i]]).M());
    }
  return r;

}

ROOT.gInterpreter.Declare(ComputeInvariantMass_code)ComputeInvariantMass_code = '''

I know there are some ways of viewing the debug, but I am unsure on how to access them on lxplus, and I am currently using VScode to code. Can anyone help me understand the error that is being thrown up?

I am posting Error message below as it is quite large.

The lines below might hint at the cause of the crash. If you see question
marks as part of the stack trace, try to recompile with debugging information
enabled and export CLING_DEBUG=1 environment variable before running.
You may get help by asking at the ROOT forum https://root.cern/forum
preferably using the command (.forum bug) in the ROOT prompt.
Only if you are really convinced it is a bug in ROOT then please submit a
report at https://root.cern/bugs or (preferably) using the command (.gh bug) in
the ROOT prompt. Please post the ENTIRE stack trace
from above as an attachment in addition to anything else
that might help us fixing this issue.

The error seems to originate from this snippet of code histo = rd.Histo2D(*h) histo.Scale( cross_section[sampleName] / tot_events * lumi ) the inside currently is just a float of 0.001 so it is essentially histo.Scale(0.001). I still don’t know what is causing the error.

Welcome to the ROOT forum !

Can you post an example reproducing you problem ? a ROOT macro …

I am currently making a compressed file with the minimal amount of code needed to reproduce this error, just having some trouble with cutting up the larger root files at the moment.
