Problem in ZMuSkimPath

[fabiocos]

In recent IBs (see CMSSW_10_2_X_2018-06-27-1500) a reproducible crash in wf 135.855 appears:

----- Begin Fatal Exception 28-Jun-2018 00:34:25 CEST-----------------------
An exception of category 'RuntimeError' occurred while
[0] Processing Event run: 315489 lumi: 89 event: 54074255 stream: 1
[1] Running path 'ZMuSkimPath'
[2] Prefetching for module PATMuonSelector/'tightMuonsForZMuSkim'
[3] Calling method for module PATMuonProducer/'tightMuonsCandidateForZMuSkim'
Exception Message:
Error, path index out of bounds
----- End Fatal Exception -------------------------------------------------

This looks likely related to the recent updates in #23636 (to be verified)

How can I reproduce it? What workflow is that?

How can I run this test? I don't see it among the tests available in runTheMatrix.py

[perrotta]

@drkovalskyi : there is a typo, in fact, in the issue description. The failing wf is 136.855, as it can be seen from the page with the failing tests in the IB:
https://cms-sw.github.io/relvalLogDetail.html#slc7_amd64_gcc630;CMSSW_10_2_X_2018-06-27-1500

@fabiocos : can you please fix the description here?

[drkovalskyi]

I don't see a failure there. I see just

136.855 RunSingleMu2018A cmd Passed Passed OtherCMS

Can someone please point me to the log of the failure or something?

[drkovalskyi]

Never mind, I found it.
