What happened?

Hello,

I have tried to download the data with the following specs


Resource:
sis-agrometeorological-indicators
Request body:
{
  "area": [
    57.181209001464964,
    9.969475411121993,
    57.16153838745902,
    10.011279434106626
  ],
  "day": [
    "01",
    "02",
    "03",
    "04",
    "05",
    "06",
    "07",
    "08",
    "09",
    "10",
    "11",
    "12",
    "13",
    "14",
    "15",
    "16",
    "17",
    "18",
    "19",
    "20",
    "21",
    "22",
    "23",
    "24",
    "25",
    "26",
    "27",
    "28",
    "29",
    "30",
    "31"
  ],
  "format": "tgz",
  "month": "01",
  "statistic": "24_hour_mean",
  "variable": "2m_temperature",
  "version": "1_1",
  "year": "2023"
}

using cdsapi code as well as the online form. With either interface, I get the same gzip file:
dataset-sis-agrometeorological-indicators-19f50da9-ba9f-4420-81aa-b65855cbd881.tar.gz

When I inspect the netcdf files with xarray I see the following:

>>> ds
<xarray.Dataset>
Dimensions:                      (lat: 1801, lon: 3600, time: 1)
Coordinates:
  * lat                          (lat) float64 90.0 89.9 89.8 ... -89.9 -90.0
  * lon                          (lon) float64 -180.0 -179.9 ... 179.8 179.9
  * time                         (time) datetime64[ns] 2023-01-01
Data variables:
    Temperature_Air_2m_Mean_24h  (time, lat, lon) float32 ...
Attributes:
    Conventions:  CF-1.7

Here the lat, lon extent is not what I asked for. It is the entire globe. I am not sure whether I do something wrong or the area is too small for the cdsapi. Any advise is much appreciated.

What are the steps to reproduce the bug?

Download the data using cdsapi with the request body and resource described above.
Use xrray to see that the extents are not the same as

"area": [
    57.181209001464964,
    9.969475411121993,
    57.16153838745902,
    10.011279434106626
  ],

Some datasets are not available for subsetting, so selecting an area is not possible and the global data will always be returned.
