scan_grib: ValueError: invalid literal for int() with base 10: '0m'

[raybellwaves]

I'm trying to read a grib file (apoligize I can't share the file) using kerchunk.grib2.scan_grib and I get scan_grib: ValueError: invalid literal for int() with base 10: '0m'

I've figure stuff out i'll update this thread.

Here the Traceback

Hmm it works with another environment. I must have a package mismatch somewhere.

Working env:
cfgrib - 0.9.10.4
eccodes - 2.28.0
kerchunk - 0.2.3

Not working env:
cfgrib - 0.9.10.4
eccodes - 2.34.1
kerchunk - 0.2.3

I seem to remember now a pinned eccodes worked for the grib files i'm working with.

Apologies for the noise.
