Using R package ecmwfr with new ADS-beta

Hi. I’m using latest R package ecmwfr to get CAMS Europe Air Quality Forecasts.
My request leads to failed status. Can anyone help me?
request ← list(
dataset_short_name = ‘cams-europe-air-quality-forecasts’,
variable = c(‘ozone’) ,
model = c(‘ensemble’),
level = c(‘0’),
date = c(‘2024-09-18/2024-09-18’),
type = c(‘forecast’),
time = c(‘00:00’),
leadtime_hour = as.character(1:6),
area = c(50.35, -2.15, 47.85, 2.20),
data_format = ‘netcdf_zip’,
target = ‘download.zip’
)
