Classifier 'AuthResult' does not have a companion object, and thus must be initialized here

[Ahmad Rodzaidi Ahmad Faiz]

Hello All,
I am facing a bit of a problem on kotlin android.
I have a problem in which this warning come up : Classifier 'AuthResult' does not have a companion object, and thus must be initialized here, when I Build-> Make Project. I have placed initialization of uAuth already before function fun() below as uAuth=FirebaseAuth.getInstance() of which the text code is colored in red. See code below. But the warning still comes out. Can someone help me is it error on putting initialization at the wrong place? Or am I missing some declaration. Your most uergent help is greatly appreciated. The language below is kotlin android. Initially the code was written in javascript. And then I convert it to kotlin android using Android Studion.

Thanks and Best Regards
