Break if nextToken is undefined.

Simple fix from debugging. Testing with Repl.

Your fix makes sense. I see the same TypeError thrown on my desktop with stack trace.

With the version from my laptop running the repl, I didn't see a trace:

% two

TypeError!
QTY ITEM                                     TOTAL
Subtotal
   Tax
Total

I didn't understand that. What else can I get you?

After npm i, the laptop shows the full error above without the receipt.
