Issues with extracting data from OpenWRF

[jendrusk]

Im trying to extract data from OpenWRF grib, and for messages with u/v wind and u/v current I'm getting errors:

ECCODES ERROR : unable to create iterator ECCODES ERROR : numberOfPoints != size(values) (12600!=12608)

I'm using file 'France_12km_WRF_WAM_210224-00.grb' you can download it from here

Steps to reproduce:

import pygrib


grb = pygrib.open("openwrf_data/France_12km_WRF_WAM_210224-00.grb")
mes = grb.message(15)
print(mes)
vals = mes.codedValues

Apparently the grib file is encoded incorrectly - the ECCODES C library is reporting that the stated grid size doesn't match the number of data values.
