404 on Content Picker on AEM publish



We have developed a page that renders a page picker with js, this works perfectly fine when we try to access it directly through ip address , we are able to see the picker, but when we try to access it through the dispatcher we are getting a 404 on "/mnt/overlay/granite/ui/content/coral/foundation/form/pathfield/picker.html?root=%2Fcontent&filter=hierarchyNotFile&selectionCount=multiple&_=1560536581894".

Any ideas on how to let the dispatcher not block this url without adding a rule?
