Yep, there it is-- the real error:
Caused by: java.lang.OutOfMemoryError: Java heap space
It seems the session-related one was just a secondary error related to trying to display the first one. I don’t know why your other example works, but perhaps the “struct” option contains less text and doesn’t take as much heap space. I’d try increasing the amount of RAM on the machine.
Thanks!
