I'm on 3.9 sorry I can do a full list of my env as I pull from an internal source but the core ones around netcdf I see

netcdf-fortran            4.5.3         
netcdf4                   1.5.7
libnetcdf                 4.8.1

Works in the pangeo docker (https://github.com/pangeo-data/pangeo-docker-images/blob/master/pangeo-notebook/environment.yml) if that helps

```
docker run -it pangeo/pangeo-notebook /bin/bash

That version should be fixed with regards to the `_FillValue type mismatch` error.
