I select my module to generate offline symbol table for and it gives me an error that the connection is invalid. And to select or create a valid connection and try again.
I have included a screenshot, the idea.log file and what I think might be a threaddump that was created around the same time I saw issue the first time.
IntelliJ 2019.1 latest build.
The reason I'm trying to rebuild is that all the objects are not being recognized, although classes are.
