I’m attempting to pass the external referrer from one function to another however it always comes back undefined. Can someone help ?

  2. import {fetch} from ‘wix-fetch’;

  3. import {ok, WixRouterSitemapEntry} from ‘wix-router’;

  5. var baseRef

  6. function myRouter_Router (request) {

  8. baseRef = request.referrer;

  10. }

  12. export function mobile_number_beforeInsert (item, context) {

  13. return fetchRequest(item);

  14. }

  16. function fetchRequest (item,request){

  18. let referrerurl = request.baseRef;

  19. }
