ungrib.exe error

Hello everyone,

I want to run the WRF model version 4.3.3 using ERA5 data. I have downloaded both pressure level data and single level data from ERA5. When I run the command ./ungrib.exe, it processes the pressure data, but it gives an error and does not process the single level data:

Start_date = 2017-07-03_00:00:00 , End_date = 2017-07-12_00:00:00
output format is WPS
Path to intermediate files is ./
*** stopping in gribcode ***\n
\tI was expecting a Grib1 file, but this is a Grib2 file.
\tIt is possible this is because your GRIBFILE.XXX files
\tare not all of the same type.
\tWPS can handle both file types, but a separate ungrib
\tjob must be run for each Grib type.\n
STOP gribsize in gribcode

I have installed WPS version 4.3.1.

I would appreciate any guidance. Thank you.
 
Please take a look at the document I attach and follow the steps to download ERA5 , then try again.

Thank you for your guidance
I did this once, but the data is very large and takes up a lot of space.
