Change of file paths - Client.Retrive does not work anymore

[CalipsoAdara]

Hello, it appears that ECMWF recently changed the file paths by adding new folders, so the "client.retrieve" function is not able to find the correct files.

Previous path (example)
https://data.ecmwf.int/forecasts/20240425/00z/0p4-beta/enfo/20240425000000-174h-enfo-ef.index

New path: (with new IFS folder)
https://data.ecmwf.int/forecasts/20240425/00z/ifs/0p4-beta/enfo/20240425000000-174h-enfo-ef.index

This change was made around the 23 of April, 2024.

Any update on this? I am also not able to re-run my earlier script that was working fine.

from ecmwf.opendata import Client

client = Client(source="ecmwf")

print(client.latest(
type="fc",
step=24,
param=["2t", "msl"],
target="data.grib2",
))

gives an error

ValueError: Cannot establish latest date for {'date': ['2024-07-11 18:00:00'], 'resol': ['0p4-beta'], 'stream': ['oper'], 'type': ['fc'], 'step': ['24'], '_url': ['https://data.ecmwf.int/forecasts']}

The above error is resolved by updating the ecmwf-opendata package to the latest version. I had to uninstall and install using pip. The file paths are automatically handled correctly by source = 'ecmwf'

client = Client(source="ecmwf")

print(client.latest(
type="fc",
step=24,
param=["2t", "msl"],
target="data.grib2",
))
