Cannot use Workbook Write Cell in system tray, however it works perfectly when starts from the studio(the process is the same one published to system tray).
It can run, but the sheet is clean.
I think I found the mistake. We should use absolute location of the excel file then publish to system tray. This is weird, when did it change?
Normally it should work with a relative path as well, as long as you consider the root folder as the one which has the project.json file in it.
