What happened?

I get wrong data shape when downloading from cdsapi compared with downloading from website.
here these shapes:

cdsapi: (721, 1440, 343)
website: (721, 1440, 366)

What are the steps to reproduce the bug?

When I change the request paramters, data shape varies. Here are the paramters:

• get shape with (721, 1440, 366)
  request = { "product_type": "reanalysis", "daily_statistic": "daily_mean", "variable": "Surface_pressure", "time_zone": "utc+00:00", "year": ["2020"], "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"], "format":"netcdf" "frequency" :"1_hourly" }

• get shape with (721, 1440, 343)
  request = { "product_type": "reanalysis", "daily_statistic": "daily_mean", "variable": "Surface_pressure", "time_zone": "utc+00:00", "year": ["2020"], "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"], "format":"netcdf" }

It seems frequency mattering. But I am comfused how frequency works.
