Minor 1) Add an external user permission THEN LOGOUT from Nuxeo => When clicking on the link in the mail, you reach:
http://localhost:8080/nuxeo/ui/workbox/workbox-sw.js#!/doc/default/85440607-86e0-422e-8b8a-8d5504a0e72a
which gives "Page not found"
2) Then, enter as URL http://localhost:8080/nuxeo
=> You reach the Home Page as the external user !
From this page, you can access the content upon whcih permission has been given.
3) Then, clicking on the link in the mail works as long as step 2 has been done
Expected: The link in the mail inviting the external user should work at step 1
