Hi there,

I am a developer that uses Office JavaScript add-in.

I've used Firebase Auth to develop Office Add-in(Excel). In my add-in, I need user to authenticate through Taskpane Dialog. It worked well around 3 weeks ago, both for Excel Desktop and Excel online(Office.com).

Today, when I started to login with Firebase Auth through Office.com, login didn't work. Although I can see auth activities from Firebase side as normal.

In the console log, I saw:

MicrosoftAjaxDS.js:1 OSF_Outil_getQueryStringParamValue: The parameter is not found.

configuration.prefetch:undefined

Please note: Excel Desktop version worked fine.

Can someone help take a look? Thanks!

B.R.

Joe
