Error in ./HomePage class HomePage_Host - caused by: Cannot read property 'uid' of null

I’m… not sure how to explain this. What can I do to avoid this from happening?

Look for something referencing a ‘uid’ property of something and make it not be null before it is referenced.

the only “uid” anywhere is the

this.firebase.currentUser.uid . I’ll see what I can do. thank you.

Any solution to this? How can I make ‘uid’ not null. The reference is this.userProfileRef = firebase.database().ref(userProfile/${firebase.auth().currentUser.uid});

Any suggestions?
