The problem is related to this line
https://github.com/cms-sw/cmssw/blob/master/Configuration/StandardSequences/python/DigiDM_cff.py#L43
(#23065)

The offending cmsDriver.py command is
step3 --datamix PreMix --conditions auto:phase2_realistic_T14 --pileup_input file:step2.root -n 10 --era Phase2C8 --eventcontent FEVTDEBUGHLT --procModifiers premix_stage2 --filein file:step1.root -s DIGI:pdigi_valid,DATAMIX,L1TrackTrigger,L1,DIGI2RAW,HLT:@fake2 --datatier GEN-SIM-DIGI-RAW --geometry Extended2026D41 --fileout file:step3.root

@makortel FYI

I think the input tag needs to be customized to DMEcalEBTriggerPrimitiveDigis using the premix_stage2 modifier

By quick look I agree (alternative would be to take a step towards resolving #26001, but that would require larger re-engineering).
