I am trying to download data from the “Fire danger indices historical data from the Copernicus Emergency Management Service” dataset. I have my own version of the API request that keeps generating an “dataset cems-fire-historical-v1 not found” error, so I tried the code directly from the API request (below) and am still receiving the same error (below).

I am able to download the “reanalysis-era5-land” data without a problem, so I know my account/etc. is functioning.

Any help would be greatly appreciated 🙂
