XpathBuilder Error

ZC Support please help.....

When I try to point the xpath builder to my ZC Rest URL I get a very long loading spin and then this.....

Error :: Invalid XML/JSON format javax.xml.xpath.XPathExpressionException

Info for you....

Using GetURL() post option...

added to paramenters

apikey = my apikey
ticket = my ticket

The above worked perfectly a couple hours ago and I made a post about it :)

What's interesting is if I put the URL together it loads fine in a browser window, but then I get this error when I take that same URL and load it into the xpathbuilder.

Please help.
