ccism_reshuffle fails with "KeyError: None" – cannot infer time coverage from CEDA-downloaded NetCDFs (ESA CCI SM v09.1, 2023)

[MauriceEric]

I am trying to reshuffle daily ESA CCI Soil Moisture data (v09.1, COMBINED, year 2023) using ccism_reshuffle. All files were downloaded via wget from the CEDA FTP server:
ftp://anon-ftp.ceda.ac.uk/neodc/esacci/soil_moisture/data/daily_files/COMBINED/v09.1/2023/

The reshuffle call fails with a KeyError: None and the warning:
ccism_reshuffle D:\ESA_CCI_SM\2023 D:\ESA_CCI_SM\reshuffled 2023-01-01 2023-12-31 --land_points True
