"Unknown file format" when trying to open ERA5 UTCI dataset

Hi everyone,
I am trying to read a netcdf file (downloaded using the code below) coming from the ER5 UTCI dataset. I am unable to read the files, both using ncview and with python. I use the same setup to open other netcdf files, including others downloaded from CDS but from other datasets (e.g. ERA5 surface data) and everything works as intended. Thank you in advance for any suggestion on how to proceed.

The code:
import cdsapi

years = [“1993”,
“1994”, “1995”, “1996”, “1997”, “1998”, “1999”, “2000”, “2001”, “2002”, “2003”, “2004”, “2005”, “2006”, “2007”, “2008”, “2009”, “2010”, “2011”, “2012”, “2013”, “2014”, “2015”,
“2016”
]

for year in years:
dataset = “derived-utci-historical”
request = {
“variable”: [
“universal_thermal_climate_index”,
“mean_radiant_temperature”
],
“version”: “1_1”,
“product_type”: “consolidated_dataset”,
“year”: year,
“month”: [
“04”, “05”, “06”,
“07”, “08”, “09”
],
“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”
],
“area”: [50, 3, 41, 16]
}

target = f"…/ERA5_UTCI_data/era5_{year}_UTCI.nc"
client = cdsapi.Client()
client.retrieve(dataset, request, target)

Was this resolved? I have the same issue.

Found the answer here Forthcoming update to the format of netCDF files produced by the conversion of GRIB data on the CDS

Yeah the issue was that I specified the file format as being .nc while it is in fact a .zip, and simply renaming it allows to then decompress and access the files.
