This branch panoskatsoulis:bmtf_eraconfig_packer_unpacker is used to create PRs for cmssw master and CMSSW_11_2_X. Bot is testing the same commit for both PRs (#32365 and #32367) , the confuses bot. I would suggest to only test it at one place or create two branches

@smuzaffar
we were testing it in the PR for the master only but after changes in the discrepancies that were seen in the tests, I was thinking of that these discrepancies might exist because of the baseline used in the tests.
For this reason, I asked to test in the backport.
