How Can I filter out (hide) a Chrome extension

[Carl]

Hello,
I am new with Fiddler.  Please bear with my inexperience. :-)
My result panel is polluted with a Chrome extension 500 error. The URL is http://127.0.0.1:55296/ChromeExt/pabeoippfoppjkpbmbpjjjglbldlajfg.  Please find a screenshot attached.

Could you please tell me what my filter options would be?
I have tried:
* Filter rule: Request header > Hide if URL contains: "/ChromeExt/pabeoippfoppjkpbmbpjjjglbldlajfg"
* Script rule:
if ( oSession.url.Contains("/ChromeExt/pabeoippfoppjkpbmbpjjjglbldlajfg") ) 
        {   
            oSession["ui-hide"] = "yup"; // "The "yup" value is unimportant"
        }

What am I missing?

Thanks in advance for your help
