catalog-builder broken after addition of grid.zarr variables in AWS

[bonnland]

The catalog builder is crashing when it tries to parse the recently added grid variables on AWS. The folder structure is not expected:

['ncar-cesm-lens', 'lnd', 'monthly', 'cesmLE-RCP85-FSNO.zarr']
['ncar-cesm-lens', 'lnd', 'monthly', 'cesmLE-RCP85-H2OSNO.zarr']
['ncar-cesm-lens', 'lnd', 'monthly', 'cesmLE-RCP85-QRUNOFF.zarr']
['ncar-cesm-lens', 'lnd', 'monthly', 'cesmLE-RCP85-RAIN.zarr']
['ncar-cesm-lens', 'lnd', 'monthly', 'cesmLE-RCP85-SNOW.zarr']
['ncar-cesm-lens', 'lnd', 'monthly', 'cesmLE-RCP85-SOILLIQ.zarr']
['ncar-cesm-lens', 'lnd', 'monthly', 'cesmLE-RCP85-SOILWATER_10CM.zarr']
['ncar-cesm-lens', 'ocn', 'grid.zarr', '.zattrs']
Traceback (most recent call last):

@andersy005 Does the grid.zarr folder need to go in ocn/monthly? Or is it intended to cover a broader group of datasets than this?

[andersy005]

Since the grid variables don't depend on time, it makes sense to just put the grid.zarr store under ncar-cesm-lens/ocn/static
