let [loading,setLoading] = useState(true);
let client = new ApolloClient({
    uri: 'https://39990dea.ngrok.io/graphql',});

let init = async () => {
    let token = await AsyncStorage.getItem('token');
    if (!!token) {
        store.dispatch(userLoaded(token));
        client = new ApolloClient({
            request: (operation) => {
                operation.setContext({
                    headers: {
                        authorization: token ? token : '',},});
            },});
        console.warn('user with token created');
        console.warn(token);
        console.warn('token is taken');
    }
    setLoading(false);
};
useEffect(init,[]);

我正在创建apollo客户端。然后，如果AsyncStorage中有令牌，则设置标头以请求令牌。

return (
<ApolloProvider client={client}>
    <Provider store={store}>
        <AppNavigator/>
    </Provider>
</ApolloProvider>

）;

但是当我发出请求时，出现Graphql错误：未显示。我在做错什么吗？
