ValueError: Chunk shape must not be greater than data shape in any dimension.

I'm trying to concatenate two Dl h5 files, but I receive the error

ValueError: Chunk shape must not be greater than data shape in any dimension. (4096,) is not compatible with (349,)

after executing

fc = FileConcatenator(list_of_input_paths, skip_errors=False)

fc.concatenate(output_path)

The paths to the files I'm using are:

/sps/km3net/users/lhennig/data_repo/data_repo_h5Dl/test/mcv6.0.gsg_anti-elec-CC_1-500GeV.km3sim.jterbr00009095.jorcarec.jsh.aanet.1448.h5Dl.h5

/sps/km3net/users/lhennig/data_repo/data_repo_h5Dl/test/mcv6.0.gsg_anti-elec-CC_1-500GeV.km3sim.jterbr00009106.jorcarec.jsh.aanet.1449.h5Dl.h5

If you don't have permissions to use them, you can find the raw files at /sps/km3net/repo/mc/atm_neutrino/KM3NeT_00000049/v6.0/reco/ by replacing ".h5Dl.h5" by ".root". Thanks in advance for your help!
