CESM 2.0.0: ERROR No default value found for ncdata

[abhirami.m]

Hello,
I am trying to run the BHIST compset with the f02_g17 (~25 km) resolution as an unsupported case using --run-unsupported in CESM 2.0.0.
During the case setup/build, I receive the following error:

ERROR: No default value found for ncdata

I understand that this may be related to the atmospheric initial condition file. However, I can see the relevant input data available in the CESM inputdata repository.
Could someone please clarify why CESM is unable to find a default value for ncdata in this configuration? Do I need to explicitly specify the appropriate ncdata file in user_nl_cam, or is there another configuration required for the BHIST + f02_g17 unsupported case?
I also tried running an FHIST case with the ne120_g17 resolution, but I encountered the following error during the CLM build stage:

CLM build-namelist::CLMBuildNamelist::add_default():No default value found for flanduse_timeseries.
I can find the corresponding .log file in the input-data repository:

https://svn-ccsm-inputdata.cgd.ucar...120np4_hist_78pfts_simyr1850-2015_c170428.log

However, I cannot locate the actual flanduse_timeseries NetCDF file. Could someone please advise whether this input file is available elsewhere, or suggest the appropriate flanduse_timeseries file/settings for an FHIST case at this resolution?

Thank you.

In this thread I will help troubleshoot the landuse question.

These are the ne120np4_hist files that I see available in the repository:

You can try one of the existing .nc files in your user_nl_clm.

Thank you very much for looking into this and listing the available files.
Could you please share the source or direct link to the repository where these files are hosted?

I think that the most relevant file based on your log name would be landuse.timeseries_ne120np4_hist_78pfts_CMIP6_simyr1850-2015_c190715.nc. I don't see this in the inputdata repository.
But it seems to be showing up in the gdex repository: NSF NCAR GDEX Dataset d651077
Try using the filter to download it.
