Error: "GRIB_API ERROR : Unknown stepType=[7] timeRangeIndicator=[7] " using eccodes

Question

I'm working with grib files from Nasa - files from NLDAS Noah model.

I'm using pygrib and grib tools (both based on eccodes engine).

When I try to get data from the file (using grib_get_data/grib_ls) or using readline (with pygrib) I get the same error:

when using grib_ls:

GRIB_API ERROR   :  Unknown stepType=[7] timeRangeIndicator=[7]
1            kwbc         surface      0            20010101     Function not yet implemented stepRange

When using pygrib:

ECCODES ERROR   :  Unknown stepType=[7] timeRangeIndicator=[7]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "pygrib.pyx", line 911, in pygrib.gribmessage.__repr__
  File "pygrib.pyx", line 1268, in pygrib.gribmessage.__getitem__
RuntimeError: b'Function not yet implemented'

I have tried to work with several different files from this model but same result.

This is the link to the NLDAS Noah model dataset: https://disc.gsfc.nasa.gov/datasets/NLDAS_NOAH0125_H_002/summary?keywords=NLDAS_NOAH0125_H

I need the data from this specific model, any suggestions what can I do? or did I miss something?
