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’  
)
