Hello I’m trying to download EFAS forecast data for 2023. This is the script that I’m using

import cdsapi

c = cdsapi.Client()

c.retrieve(  
‘efas-forecast’,  
{  
‘format’: ‘netcdf4.zip’,  
‘system\_version’: ‘operational’,  
‘originating\_centre’: ‘ecmwf’,  
‘product\_type’: ‘high\_resolution\_forecast’,  
‘variable’: ‘river\_discharge\_in\_the\_last\_6\_hours’,  
‘model\_levels’: ‘surface\_level’,  
‘year’: ‘2023’,  
‘month’: [  
‘01’, ‘02’, ‘03’,  
‘04’, ‘05’, ‘06’,  
‘07’, ‘08’, ‘09’,  
‘10’, ‘11’, ‘12’,  
],  
‘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’,  
],  
‘time’: [  
‘00:00’, ‘12:00’,  
],  
‘leadtime\_hour’: ‘72’,  
},  
‘download.netcdf4.zip’)

However I got the following message:  
2024-06-28 16:21:58,468 INFO Welcome to the CDS

During handling of the above exception, another exception occurred:

Could you help me please in fixing this problem?
