I'm running through the 30 days of graph series. I've downloaded and configured the various files as per the instructions, I am at the stage of running http-server and then opening my browser (using the http://127.0.0.1:8080 url).

I click the link for V2 Endpoint (Javascript) and I see a Sign In button.
I click the Sign In button and popup appears.
I try to login
I get the following error message:

AADSTS50194: Application 'XXXXXXXX' is not configured as a multi-tenant application. Usage of the /common endpoint is not supported for such applications created after '10/15/2018'. Use a tenant-specific endpoint or configure the application to be multi-tenant.

Am I missing a step in the code somewhere? I note in the file index.2a.html on lines 39/40:

            //Pass null for default authority (https://login.microsoftonline.com/common)
        var myMSALObj = new Msal.UserAgentApplication(applicationConfig.clientID, null, acquireTokenRedirectCallBack,

Should this line be tweaked? Should I have configured the App Reg to be multi-tenant?
