Redirect to /auth/null after /external_logout request

[wert93]

The issue I am facing is that after logging out of a session opening the url localhost:3000/auth/external_logout?_method=DELETE&client_id={clientID}&redirect_sign_out_uri=http://localhost:60606/ from my web app hosted on localhost:60606 (but the same happens manually inserting the url in the browser) I correctly sign out of the application, but I am redirected to localhost:3000/auth/null. If I set my web app to open the url in a new page I am able to return to my web app home on http://localhost:60606/ , but a tab still opens on /auth/null.
