Add '\' where? Can you show us that line which causes the trouble?

I have formatted the code (OP just didn't have any code tags)

In Javascript, when you write the literal string:

JavaScript

var s = 'click the \"Setup\" button';

you create a string that contains:

click the "Setup" button

When you pass that string to JSON.parse, it sees the first " as the end of the string. It's then expecting to see a , or a }, as it's reached the end of the property value, but instead it finds the identifier Setup.

You have to escape the \ character so that it's included in the string passed to JSON.parse:
