Juno debugger in Atom - Numerous problems interacting with debug session, like ArgumentError invalid index, UndefVarError, etc

I am trying to use the debugger that comes with JuliaPro 1.2.0-1. This collection of software provides an IDE (Atom) and a debugger ("Juno", or something).

A create a new .jl file containing only

function test()
    a = 1
    b = 2
end

And put a breakpoint on line 2, a=1.

I then either copy and paste it into the REPL (interactive julia pane), or select the code and hit Ctrl+Enter to do the same.

Now test() is defined in the REPL session. I then open the debugger. Now everything looks like below:

After a lot of trouble with poor documentation, I figured out how to start the debugging session by executing Juno.@enter test() in the REPL window. I do so, and it hits the breakpoint supposedly:

I then want to to interact with the variables inside test(). Such as calling print(a). It prints, but then some weird error occurs:

If I just type a, I get:

Supposedly c and fm are commands in the debug session, but they don't work.

So I'm completely confused. Is the debugger broken? Am I using it incorrectly? Thanks for your help.

Figured out the problem. JuliaPro simply doesn't have a working debugger. There is some conflict or outdated versions of the packages, causing the above problems.

I uninstalled JuliaPro, and instead installed julia, Atom text editor, and finally Juno through the text editor using this guide. Now print(a) and a both work as expected in the debug> session. However commands c and fm still don't work, and I'm not sure why (edit: see @pfitzseb comment).
