Description

Hi there!

I'm getting the following error in chrome console:

GET https:/login.microsoftonline.com/{TENANT_ID}/oauth2/v2.0/undefined 404

For some reason it is sending a GET request with a /undefined attached to the end of it.

Therefore I cannot authenticate and use my application. It was working fine until today
