Failing to retrieve data via cdsapi client


Hi, I am using the cdsapi python package to load era5 data.

I am basically doing


cds_client = cdsapi.Client(quiet=False, url=url, key=key, verify=True)
params = {'product_type': 'reanalysis',
'time': ['00:00', '01:00', '02:00', '03:00', '04:00', '05:00', '06:00', '07:00', '08:00', '09:00', '10:00', '11:00', '12:00', '13:00', '14:00', '15:00', '16:00', '17:00', '18:00', '19:00', '20:00', '21:00', '22:00', '23:00'],
'format': 'netcdf',
'grid': [0.25, 0.25],
'variable': 'total_precipitation',
'dates': ['2022-11-10'],
'area': [x, x, x, x]}
fl = cds_client.retrieve("reanalysis-era5-single-levels", params)

(I replaced the area data by x's)

leading to

This exact procedure worked before. The last time it worked for me was on the 5th of December. Does someone have an idea what is going wrong?
Thanks a lot in advance!




After some experimenting I found the issue: In the parameters, if I replace 'dates': ['2022-11-10'] with 'year': 2020, 'day': '10', 'month': '11', everything works nicely.

It seems like there was an update on the 5th of December on the server that broke the ability to query with the 'dates' parameter, which also raises a weird error message.

Hello,

Thank you for the message. I have the same issue with "dates".

My script was working but 

 r = c.retrieve(
        'reanalysis-era5-single-levels',
        {
            'variable': ['10m_u_component_of_wind', '10m_v_component_of_wind', '2m_dewpoint_temperature',
                         '2m_temperature', 'total_cloud_cover'],
            'product_type': 'reanalysis',
            "dates": "2022-01-01/to/2022-01-05",
            'area': cg.africa_zone,
            'time': [
                '00:00',
                '03:00',
                '06:00',
                '09:00',
                '12:00',
                '15:00',
                '18:00',
                '21:00',
            ],
            'grid': '0.25/0.25',
            'format': 'netcdf'
        })


 "dates": "2022-01-01/to/2022-01-05", is not working. How to put a period now.

Hi Tim, Henri

Its best to use the keywords as shown on the CDS download page for a given dataset - in this case  'year', 'day', 'month', is the best form to use for specifying dates,

Thanks,

Kevin
