In an HA Environment, sometimes or possibly always, when running the debugger on an Action there is blank screen and it appears that the debugger is not running at all.
When the debugger is run, it creates a temporary file in
/var/run/cloudbolt/tmp . If you are in an HA environment this could be sent to the other server than you are currently interacting with in the UI.
All that is needed is to add one more path to the NFS share:
Once this path is added to your NFS share, the debugger will now properly populate with the python script and will be able to step through the code.
