./preview_namelist error: "out=setting clm_usr_name -- but did NOT find any user datasets"

[liren]

Hello everyone,

I am running CTSM/CLM5.0 single point simulation using the compset "I1PtClm50SpGs". I have set the "*.xml" files and setting the "user_nl_clm":

fsurdat="/ddn_lustre/weiliren/CESM-release-cesm2.1.3/cime/output/inputdata/lnd/clm2/surfdata_map/surfdata_1x1_Umpqua_hist_78pfts_CMIP6_simyr2000_c230921.nc"

When running "./preview_namelist", an error occurs:

Setting resource.RLIMIT_STACK to -1 from (-1, -1)

err=

I'm pretty sure about the domain file, surface data and forcing data path are correct.

Also I have seen this thread: ./preview_namelist error CLM build-namelist::CLMBuildNamelist::add_default() : No default value found for fsurdat. However, my error is slightly different with their error message: there is no "err=" message shows in my error code. So I don't know why this error occurs...

Any advice may be helpful to my problem! Thank you very much!

Well ... Without any modification and reason, this error disappears and I don't know why
