Office-Add-in-Microsoft-Graph-React Sample example - First try = Login is already in progress about office-add-in-samples HOT 5 CLOSED

Hi
I've found a way to trigger this consistently after the Add-in is setup. And a workaround to bypass the error.

Triggering the error

If I change (or remove) the Redirect URIs in SPA setup in Authentication in the AAD App I can trigger the usual

Sorry, but we’re having trouble signing you in.
AADSTS50011: The reply URL specified in the request does not match the reply URLs configured for the application

error, as expected.
Now I can close the popup, change the Redirect URIs back to the valid URI and trigger login (signInO365) which should work, but I get the error as described in this issue.

Bypass error

To bypass this I clear cookies (on my domain), not localStorage or sessionStorage, but cookies.
MSAL will create a bunch of non-HttpOnly cookies, and by clearing these the login will work as expected.
There is a bug in the sample, where the Promise from msalInstance.loginRedirect is ignored, this is where I add a catch and do something like this: https://stackoverflow.com/a/179514 .
I tried to find some "clear" method in MSAL, but didn't see anything.

Hi @inspiraller and @eirikb,

Yes, following @eirikb's repo steps I see this same problem. @inspiraller does clearing the cookies fix the issue for you? I'm checking with the team to see if there's a better solution. Thanks!

Hi @inspiraller,

I apologize as I missed an important detail in your repo steps. Your steps indicate that you configured a web redirect. You need to use an SPA redirect since this sample is a single-page application. You can configure this from the Redirect URIs links on the Overview page in your App registration on the Azure portal. This will take you to the Platform configurations page where you can Add a platform and then choose Single-page application.

Hope this helps,
David
