Observable' is not assignable to type 'AngularFireList'
1
I am working with Angular7, Angularfire2 5.1.0 and Firebase 5.5.8. After code a demo app I had the error:
"ERROR in src/app/app.component.ts(13,5): error TS2322: Type
'(events?: ChildEvent) => Observable<>' is not assignable to
type 'AngularFireList<>'. Property 'query' is missing in type
'(events?: ChildEvent) => Observable<>'."

I said you must subscribe. Here is an example:
this.db.list('/customers').valueChanges().subscribe((datas) => console.log("datas", datas) ,(err)=> console.log("probleme : ", err) );
