NPE with multidimensional GRIB2 file with time and custom dimension

Description

When loading GRIB2 files downloaded from the National Hurricane Center forecast data ( https://ftp.nhc.ncep.noaa.gov/wsp/ ), I get a NPE from within the NetCDF parser:

This most often happens when loading the layer in GeoServer, but I've also encountered it when trying to view any time dimension other than the first, in which case I see a similar error:
