CDS-Beta downloads files in a different format (grib) than original cds (netcdf4)

Software and Tools API
1

The following code downloads a zip file containing a grib file if running with CDSBeta.

It download a zip file with a netCDF4 if run with the old credentials.

Is this a bug? Is it related with the chenges on the netCDF converter?
Thank you

import cdsapi

NEW = True

if NEW:
    url = 'https://cds-beta.climate.copernicus.eu/api'
    key = XXXXXXXXXXXX
else:
    url = 'https://cds.climate.copernicus.eu/api/v2'
    key = XXXXXXXXXXXX


c = cdsapi.Client(url=url, key=key)

c.retrieve(
    'efas-forecast',
    {
        'format': 'netcdf4.zip',

Have you tried using ‘netcdf.zip’ instead of ‘netcdf4.zip’? It is working fine for me using the former.

I believe these are the options for format: “grib”, “netcdf.zip”, or “netcdf”. The default is grib, which would be output if the format parameter is incorrect.

[EDIT]
It appears they have changed the format parameters in the Beta version. I am reading two required parameters now: “data_format” and “download_format”

To download as a netcdf.zip, the parameters should be formatted in your dictionary as follows:

‘data_format’: ‘netcdf’,
‘download_format’: ‘zip’,

Thank you very much for your help! I tried again today, but now I always get the following error, no matter what format or data_format I specify:

requests.exceptions.HTTPError: 404 Client Error: Not Found for url: https://cds.climate.copernicus.eu/api/retrieve/v1/jobs/630be6d8-56f6-4725-9d34-2f0a980ecf92?log=True&request=True
job not found
job 630be6d8-56f6-4725-9d34-2f0a980ecf92 not found

I think this is related to the decommission of the old API.
