CMIP6 Unable to parse the time values entered

[mendezr]

I want to download CMIP6 a subset data between two dates using the cdsapi but didn't have success.

I tried to download with this configuration:

c.retrieve(
    'projections-cmip6',
    {
        'temporal_resolution': 'daily',
        'experiment': 'ssp5_8_5',
        'level': 'single_levels',
        'variable': 'precipitation',
        'model': 'cmcc_esm2',
        'date': '2020-01-01/2050-01-01',
        'format': 'zip',
    },
    'download.zip'

When I run the code below, got this error:

Also tried to use the toolbox request and got this error:

If I didn't select the date parameter (the whole available temporal range), the API works and the file is downloaded.

Many thanks
