cannot read property 'getCookieString' of undefined. How do I fix this? Trying to install an app

function clearCookies(wildcardDomain=false, primaryDomain=true, path=null){

    pathSegment= path ? '; path=' + path : ''

    expSegment="=;expires=Thu, 01 Jan 1970 00:00:00 GMT"

    document.cookie.split(';').forEach(

        function(c) { 

            primaryDomain && (document.cookie = c.replace(/^ +/, "").replace(/=.*/, expSegment + pathSegment))

            wildcardDomain && (document.cookie = c.replace(/^ +/, "").replace(/=.*/, expSegment + pathSegment + '; domain=' + document.domain))

         }

     )

}
