Root files that have `.1` apaended to name fail to open

The following query:

calratio_x_dsname = "mc16_13TeV:mc16_13TeV.311425.MGPy8EG_A14NNPDF23_NNPDF31ME_HSS_LLP_mH1000_mS50.deriv.DAOD_EXOT15.e7357_e5984_s3234_r10201_r10210_p4696_tid26710934_00"

# Because we aren't running calibrations for tracks, I hope R25 code works on this!
from func_adl_servicex_xaodr25 import FuncADLQueryPHYSLITE

query = FuncADLQueryPHYSLITE().SelectMany(
    lambda e: e.TrackParticles("InDetTrackParticles").Select(
        lambda t: {"pt": t.pt(), "eta": t.eta()}
    )
