sst_update of ERA5 in wrf.exe

[leezf]

Hi,
I am a greenhand of WRF. I am trying to use ERA5 data to simulate a specific typhoon. But when I used ERA5, I found that the Sea Surface Temperature didn't change over time.When I set sst_update = 1 and edit related options in namelist.input, the WRF model didn't work because of an error "Possibly missing file = auxinput4".I want to know how to deal with this problem, thanks.
My namelist.input and rsl.out.0000 has been attached below.

I think you need to re execute real.exe to extract the relevant lower boundary conditions from the met file.

Which file should I attach? I have re-executed real.exe.

Try the settings from manual and re-executed again:

auxinput4_inname = "wrflowinp_d<domain>",
auxinput4_interval = 360,
io_form_auxinput4 = 2
