SSO CORS error when performing user re-authentication

[PedjaCucak]

Hi,

I forked your code, and host the app on Azure with Microsofr Identity provider, with implicit flow.
I have notice that when cookie "AppServiceAuthSession" expires (it gets removed from browser) and if I try to generate new answer "/generate" api it will return 302 with redirect routh (Location) as below

https://login.microsoftonline.com/.../authorize?...&state=redir%3D%252Fhistory%252Fgenerate

This api fails with CORS error.

I tried to copy/paste this url to browser tab and delete "&state=redir%3D%252Fhistory%252Fgenerate" url param from it, and then re-login works.

Do anyone know why this redirect url doesn't work, and where it gets created?

Any help is appreciated.

Thank you for your help in advance.
