getAccessToken fail, interaction_required/AADSTS160021

[krzysztof-plutoflume]

We have noticed occasional failures when trying to obtain an SSO access token.

The call

await OfficeRuntime.auth.getAccessToken({ allowSignInPrompt: true });

fails and there's no errorCode/errorMessage on the exception.

We can see that internally there's a redirect being performed to
https://outlook.office.com/mail/spaExtSSO.html#error=interaction_required&error_description=AADSTS160021%3a+Application+requested+a+user+session+which+does+not+exist.

Can you provide some more information about this error?

Your Environment

• Platform [PC desktop, Mac, iOS, Office on the web]: Office on the web
• Host [Excel, Word, PowerPoint, etc.]: Outlook
• Office version number: N/A
• Operating System: Windows, macOS
• Browser (if using Office on the web): Edge, Chrome

Expected behavior

The access token can be obtained successfully.

Current behavior

The getAccessToken call fails with no error message/code, as described above.

Steps to reproduce

I don't currently have reliable steps to reproduce this issue.

Hi @krzysztof-plutoflume,

Hi, thank you for reaching out. In order to debug further, could you please reproduce the issue and collect logs. Steps to collect logs is captured here - https://github.com/OfficeDev/office-js/wiki/Collecting-log-files-for-Outlook-Add%E2%80%90ins-issues and give the access to exextoc.
Most likely, it is happening due to the token getting expired (which is valid for ~1 hour).

Also, please let us know

1. If you call getAccessToken again,are you able to get the token or do you need to refresh the add-in?
2. Any errors office.js is throwing?

[krzysztof-plutoflume]

I will update the issue with logs if I manage to reproduce again. As I said, I don't have a way to consistently reproduce, I was hoping that the error message from the redirect would help shed some light on the problem

@krzysztof-plutoflume Can you check following:

• Is there any pattern they see, like does this occur when the client is inactive for long time? In that case the current session might have gone stale for some reason
• What happens if we refresh and clear cache?
• Can you check if any popups are being blocked by the browser when this issue occurs?"
