在React Native中从抽屉导航器重置堆栈导航器时，没有为键定义路线

Question

我正在制作一个react native应用程序，其中有一个包含所有导航器的主文件。这是我的应用程序的主堆栈。

const RootStack = createStackNavigator({
  Splash : { screen: Splash },
  ModelProfile: { screen: ModelProfile},
  HomeModel: {screen: modeldrawerNavigator},
  EnterOtp : { screen: EnterOtp},
  OtpChangePassword : { screen: OtpChangePassword},


}, {
     headerMode: 'none',
     initialRouteName: 'Splash'

})

const AppNavigator = createAppContainer(RootStack)
export default AppNavigator;

这里是modeldrawerNavigator

const modeldrawerNavigator = createDrawerNavigator(
  {
  HomeScreen: { screen: homeStack},
  EditProfile : { screen: profileStack},
  BuyStar : { screen: StarStack},
  Notifications : { screen: nStackmodel},
  ResetPassword : { screen: ResetPassword},

  },
  {initialRouteName: 'HomeScreen',
  gesturesEnabled: true,
    contentComponent: props => <DrawerModel {...props} />
  },

);

StarStack是

const StarStack = createStackNavigator({

  Buy : { screen: BuyStars},
  PaymentMode : { screen: PaymentMode},

 }, {
    headerMode: 'none',
    initialRouteName: 'Buy'

 });

当有人单击BuyStar时，现在在抽屉导航器中，我必须重置星号堆栈 这是我的代码

<TouchableOpacity onPress={() =>{
              this.props.navigation.navigate('BuyStar');
              const resetAction = StackActions.reset({
              index: 0,
              actions: [NavigationActions.navigate({ routeName: 'Buy' })],
            });

            this.props.navigation.dispatch(resetAction);
            }}>
            <Text style={styles.drawertext}>Buy Stars</Text>
            </TouchableOpacity>

但这给了我

错误

No route defined for key 'Buy',Must be one of 'Splash','EnterOtp' etc.

请帮助我解决此问题。
