create_newcase not working

I'm trying to run a regional GMOM case. I had it making new cases, but now it's not working and I don't know what I did to break it. The current failure:
```
(NPL) cheyenne5 277% ./create_newcase --res TL319_Bering --compset 2000_DATM%JRA_SLND_CICE_MOM6_SROF_SGLC_SWAV_SESP --case Bering_JRA_2.2 --run-unsupported --driver nuopc
Compset longname is 2000_DATM%JRA_SLND_CICE_MOM6_SROF_SGLC_SWAV_SESP
Compset specification file is /glade/u/home/kate/CESM/components/mom//cime_config/config_compsets.xml
Did not find an alias or longname compset match for 2000_DATM%JRA_SLND_CICE_MOM6_SROF_SGLC_SWAV_SESP
ERROR: Could not initialize Grids
```
Any suggestions?
 
To follow up, I ran in pdb and got enough information to fix things. Order matters in the grid file:

<domain name="Bering">
<nx>237</nx> <ny>277</ny>
<file grid="ocnice">/glade/work/kate/mom.input/Bering/domain.ocn.Bering.200527.nc</file>

<mesh driver="nuopc">/glade/work/kate/mom.input/Bering/Bering_SCRIP_200527_ESMFmesh.nc</mesh>
<desc>Bering Sea domain at 10 km ocean-ice grid:</desc>
<support>For MOM6 experiments with coupled ice</support>
</domain>


I had had mesh at the end.
