ERA5 data of Ocean Waves

I’m trying to download ERA5 ocean wave data using the “short name,” such as “swh.”
However, the downloaded data is not “swh.”
See below. Is it not possible to download ERA5 data using the short name?

1:0:d=10010200:IEWS:sfc:anl:type=analysis:NAve=0
2:2076588:d=10010203:IEWS:sfc:anl:type=analysis:NAve=0

Hi,
please use the relevant webform on the Climate Data Store (CDS) to build and check the syntax of your API request:

Thanks for reply.

I’m wondering why variables such as 10u and 10v can be downloaded using their short names, while the ocean-wave variables cannot be downloaded with short names like “swh.” This inconsistency seems strange to me.

Thanks
