Describe the bug

When I write to datastore I got this error:

[ERROR] 43:57.200 DataStore - Object is not an instance of a valid model, Object {
  "model": Event {
    "description": "Lorem ipsum dolor sit amet",
    "name": "Lorem ipsum dolor sit amet",
  },
}

Expected behavior

I expect that it will write to the datastore

Reproduction steps

I have followed these instructions https://docs.amplify.aws/lib/datastore/getting-started/q/platform/js/

I have this schema:

type Event {
  id: ID!
  name: String!
  description: String
}

And this in my app.js


import { StatusBar } from "expo-status-bar";
import React, { useEffect } from "react";
import { SafeAreaProvider } from "react-native-safe-area-context";

import useCachedResources from "./hooks/useCachedResources";
import useColorScheme from "./hooks/useColorScheme";
import Navigation from "./navigation";
import { DataStore, Analytics, Auth } from "aws-amplify";
//import { DataStore } from "@aws-amplify/datastore";
import { SQLiteAdapter } from "@aws-amplify/datastore-storage-adapter";
import { Event } from "./src/models/index";
import { withAuthenticator } from "aws-amplify-react-native";
import Amplify from "aws-amplify";
import awsconfig from "./src/aws-exports";

Analytics.disable();
Amplify.configure(awsconfig);
window.LOG_LEVEL = "DEBUG";
DataStore.configure();

function App() {
  const isLoadingComplete = useCachedResources();
  const colorScheme = useColorScheme();

  useEffect(() => {
    const test = async () => {
      await DataStore.save(
        new Event({
          name: "Lorem ipsum dolor sit amet",
          description: "Lorem ipsum dolor sit amet",
        })
      );
    };

    test();
  });

  if (!isLoadingComplete) {
    return null;
  } else {
    return (
      <SafeAreaProvider>
        <Navigation colorScheme={colorScheme} />
        <StatusBar />
      </SafeAreaProvider>
    );
  }
}

export default withAuthenticator(App);
