cmssw: Mini-v2 can not be produced in FastSim UL scenario

Hi,

[Description]: we are closing the setup for RunII FastSim campaigns under UL scenarios. In our tests, Mini-v1 works just fine. However, Mini-v2 doesn’t.

[Error]: ----- Begin Fatal Exception 04-Aug-2021 13:20:35 CEST----------------------- An exception of category 'ProductNotFound' occurred while [0] Processing Event run: 1 lumi: 1 event: 1 stream: 0 [1] Running path 'MINIAODSIMoutput_step' [2] Prefetching for module PoolOutputModule/'MINIAODSIMoutput' [3] Prefetching for module PATElectronSlimmer/'slimmedLowPtElectrons' [4] Prefetching for module PATElectronSelector/'selectedPatLowPtElectrons' [5] Prefetching for module PATElectronProducer/'patLowPtElectrons' [6] Calling method for module LowPtGsfElectronIDProducer/'lowPtGsfElectronID' Exception Message: RefCore: A request to resolve a reference to a product of type 'std::vector<reco::Track>' with ProductID '1:982' can not be satisfied because the product cannot be found. Probably the branch containing the product is not stored in the input file.

[How to reproduce]:

• Mini-v1 (working): wget https://cms-pdmv.cern.ch/mcm/public/restapi/requests/get_test/PPD-RunIISpring21UL16FSwmLHEGSPremix-00001 this will produce AODSIM, since FastSim. For more quick test, edit the EVENTS variable of the script to have less events wget https://cms-pdmv.cern.ch/mcm/public/restapi/requests/get_test/PPD-RunIISummer20UL16MiniAOD-00009

• Mini-v2 (issue): wget https://cms-pdmv.cern.ch/mcm/requests?prepid=PPD-RunIISummer20UL16MiniAODv2-00008&page=0&shown=127 this will use the same AODSIM from the above (mini-v1) recipe

Could you kindly advise on how should we deal with mini-v2 scheme if possible at all considering that this is FastSim, please?

Thanks, Jordan for PdmV
