Debugging Issues

Scripting
1

I’m only able to debug a script below the include lines in a workspace if the variable tab isn’t open. As soon as I open the variable tab, the debug will terminate. This is an error message I received on the console after attempting to debug the list logical components sample script:
py4j.Py4JException: An exception was raised by the Python Proxy. Return Message: Traceback (most recent call last):

We have experienced the same issue on our side, For the moment I don’t know what is causing this issue. You can experiment by changing the debug engine used by EASE to debug the Python code, but I’m not sure it will help. If you fine a solution to this issue let us know.

For the second stack you can have a look at the following issue:
