Blank output net shortwave radiation

Hello everyone,
The output of estimate net shortwave radiation shows a blank output. The minimum and maximum values are 0. I am not being able to understand where is the problem. Can someone help me?
I am using windows 10 snap 7 configured with python 3.6.3.
The landcover product was downloaded manually and then performed collocate with respect to the output mask. I have calculated aerodynamic roughness with this landcover product and it shows outputs with correct values. Now i cannot understand where is the problem.
Thanks in advance.

I have the same problem. did you find a solution for it?
Thank you in advance.

Are you sure that your are doing the analysis during daytime and not nighttime, i.e. the sun zenith angle values are positive.
