@SorooshMani-NOAA suggested checking version of packages.

esmpy                     8.4.2              pyhc1e730c_4    conda-forge 

conda list | grep cf

cf-python                 3.16.1          py310hc57ae4c_0    conda-forge

cffi                      1.16.0          py310h2fee648_0    conda-forge

cfunits                   3.3.7              pyhd8ed1ab_0    conda-forge

The only difference with Soroosh's environment was cfgrib 0.9.13.0 (instead of 0.9.12.0)

[FariborzDaneshvar-NOAA]

I changed cfgrib version (conda install "cfgrib=0.9.12.0") and re-ran the workflow, but it failed again with the same error!

For the record, similar issue: ESMValGroup/ESMValTool#3208

[FariborzDaneshvar-NOAA]

@thanks to @SorooshMani-NOAA for looking into this. I updated importlib_metadata (mamba install -cconda-forge "importlib_metadata<8"), and re-ran it. Problem solved.
