./preview_namelist error CLM build-namelist::CLMBuildNamelist::add_default() : No default value found for fsurdat.

Hi there,
I've ported CIME to my local machine, I've changed the config_machines.xml file which is located in $CIMEROOT/cime/config/cesm/machines/, then I also changed the config_compilers.xml file in the same path.
and I run ./create_newcase --case test_8.10 --res CLM_USRDAT --compset I1PtClm50SpGs --mach centos7-linux --run-unsupported
then I modified the env_run.xml setting the "RUN_STARTDATE","STOP_N" and I set ''ATM_DOMAIN_FILE'', '"ATM_DOMAIN_PATH", "LND_DOMAIN_FILE" and "LND_DOMAIN_PATH" to the same domain file and path created by the specific observation tower data. and set "CLM_USRDAT_NAME" to my observation tower name.
then I run ./case_setup , there is no error.
and the next step I modified the user_nl_clm by adding

hist_nhtfrq = -24
hist_mfilt = 486

and adding

streams="datm.streams.txt.CLM1PT.CLM_USRDAT 2017 2017 2018"
"datm.streams.txt.presaero.clim_2000 1 1 1"

to user_nl_datm .
then I run ./preview_namelist, which got the error I'm confused about:

err=ERROR : CLM build-namelist::CLMBuildNamelist::add_default() : No default value found for fsurdat.
Are defaults provided for this resolution and land mask?

I'm pretty sure about the domain file and path are correct, so in my opinion, Is this some kind of connection with the "surface_dataset" error which I didn't modify in env_run.xml or some other namelist file? is there some log file contains the details of this error? and how I suppose to correct this error?

and I've changed "CLM_USRDAT_NAME" to 1x1_MADUO, but why
setting clm_usr_name -- but did NOT find any user datasets: 1x1_MADUO
and why after I run preview_namelist, it will still create the
clmconf datmconf datm.input_data_list
in Buildconf?

ps: I attached the file I modified

You need to add the path to your surface dataset in the user_nl_clm file.

So add

fsurdat = '<path to the surface dataset for your surface dataset for the 1x1_MADUO site>

You'll also need to make sure the datm streams files point to the right datasets for your atmosphere forcing data.

thanks for this solution!
I will try to add fsurdat to my user_nl_clm and rerun preview_namelist

thanks a lot agin!

sorry to interrupt you again,
I added

fsurdat = /home/clm5.0/inputdata/lnd/clm2/surfdata/surfdata_1x1_maduo_simyr2000.nc

and retyped ./preview_namelist, it comes to another error:

[root@CentOS8 test_8.10]# ./preview_namelists

is this means that my surfacedata''surfdata_1x1_MADUO_simyr2000.nc'' has something wrong??

You need single quotes around your path, i.e.,:

fsurdat = '/home/clm5.0/inputdata/lnd/clm2/surfdata/surfdata_1x1_maduo_simyr2000.nc'

Thanks a lot!!!
it accomplished perfectly after I add single quotes.
