Facing problem while using era5 data to run WRF-Chem model


Dear all,
I would like to run the WRF-Chem model with era5 data. However, after downloading both the pressure level and surface level, I could not run ungrib.exe.
Below is the error message I got after running ungrib.exe:
*** Starting program ungrib.exe ***
Start_date = 2021-01-14_00:00:00 , End_date = 2021-01-31_00:00:00
output format is WPS
Path to intermediate files is ./
End-of-record mark (7777) not found-632652727
Sec0(1) = 26214508 0
*** stopping in findgrib in gribcode ***\n
\tI could not find the GRIB string in the input file
\tafter testing the first 100,000 bytes.
\tThe file may be corrupt or it is not a GRIB file.
\tPerhaps a gzipped GRIB file or netcdf?\n
STOP findgrib

To remove this error I followed the instructions suggested from the link below, but the same error message appeared after running ungrib.exe.

I used both erainterim and ecmwf vtable to run the ungrib.exe but did not change.

so how can I remove this error message, please?
I also attached my wps namelist.
