You have used SP.RequestExecutor which is used for making cross domain calls and if so your _spPageContextInfo.webServerRelativeUrl won't work. Either you need to use query string to get the url or try using hard code url value. For getting url from query string

hostweburl =
appweburl =

var scriptbase = hostweburl + "/_layouts/15/";

With regards to the error your encountering , I believe you want to change your call to _spPageContextInfo.webServerRelativeUrl to _spPageContextInfo.siteAbsoluteUrl

The following article provides a good breakdown on the properties available on _spPageContextInfo
