empty values downloading .nc data from ERA5 Land (0.1*0.1) using the tool box

Hi,

I'm having trouble using the toolbox to download netcdf formats of temperature data. I used the following toolbox script to download 2m_temperature. The variable "t2m" in the returned data contains mostly missing values, whereas if I use "submit form", the "t2m" variable is correct and complete. Does anyone know how to solve this problem?

Thanks,

tori
