Error "No results found: definitions for 1 gauss points read"

[Beginner]

Hello,
I am a beginner to CODE_BRIGHT. I am still going through the tutorials. In tutorial No. 2: thermal problem, when I try the time varying flux condition the following error appears in the post process (No results found: definitions for 1 gauss points read). I followed the instructions as stated in the tutorial manual. I am using CODE_BRIGHT (2023_05) and GiD (x64 16.0.5). I noticed that the tutorial manual was intended to an earlier version (i.e. 2022). Did the procedure for applying a time varying boundary conditions change in the 2023 version?

Thank you for your help.
