Why is there no debug console output?

[jyelon]

When I type an lldb command into vscode 'debug console', I get error messages, but I don't get valid output. Here's an example session:

print 3
error: Process is running.  Use 'process interrupt' to pause execution.
print 3

fnord 3
error: 'fnord' is not a valid command.
help

print 3

So as you can see, the commands that are valid produce no output, but the ones that are invalid lldb commands produce error messages. I should also mention that the 'watch' and 'variables' windows are working. I can tell that lldb is receiving my commands, because otherwise, there would be no error messages.

So where's the valid output? Where could it be going?
