Problem with index_description regex

I am working to do a site ini. I found a strange issue with regex in WebGrabPlus although regexr.com states I've found a match fine. I am using a lazy match for your information.

index_description.scrub {regex(debug)||\"Short_descr\"\:\"(.*?)\"||}


The logs say that there is no match

[ Debug ] Debugging information SiteIni
[ Debug ] Element: INDEX_DESCRIPTION
[ Debug ] html source written to : /home/akmalharith1/iptv/wg++/.wg-test/./html.source.htm
[ Debug ] scrub strings:
[ Debug ] type & arguments : regex(debug)
[ Debug ] regex_expression : "Short_descr\"\:\"(.*?)\"
[ Debug ] !! No match found !!


Please see the screenshot below. Sorry if the image is too big for this forum. Am I missing anything? I am very close to completing this ini which I have been working on for weeks now.

Thanks guys in advance. :-)
