Hello. I’m running Juno debugger and everything works fine except when I’m trying to run any command/evaluate a variable or expression etc in debugging mode (under the “debug\>” prompt), I get the following error:

ERROR: ArgumentError: invalid index: Symbol(“#self#”) of type Symbol

Any idea how to fix this?

Thanks,

-Victor
