I am getting an error with this too.

this.db.list<Player>("/Players").valueChanges().subscribe((data) => { list = data; });

The error I'm getting in the console is

TypeError: Object(__WEBPACK_IMPORTED_MODULE_1_rxjs__["of"]) is not a function. (In 'Object(__WEBPACK_IMPORTED_MODULE_1_rxjs__["of"])(snapshotAction)', 'Object(__WEBPACK_IMPORTED_MODULE_1_rxjs__["of"])' is an instance of Object)
