Description

The view "Directory Tree" does not work, I only see the top directory of my scan. If I want to open/expand it, a "Processing.." pops up very short and the "expand icon" dissapears.
Are there any known issues?
Do I have to consider anything (e.g. dir of json-file, dir of running scancode-workbench)?

System configuration
