Edit: I don't know what caused it, but the problem seems to have magically solved itself

Hi,

I am trying to download daily statistics of the ERA5 dataset using the application for the toolbox. Running the request remotely from a python environment, downloading the data on single levels was no problem. However, the request for the pressure level data produces a lengthy error message which I do not understand. I've added the error down below and attached my script for reference.

Any suggestions on how to solve this would be greatly appreciated.

Hi Pim,

Suspect it was a temporary issue with the CDS. Glad it is working for you now!
