Possible Unhandled Promise Rejection (id: 3):

Question

I am developing a project through which a user can upload media files to Amazon AWS S3 storage and can manipulate it later. But it giving me a warning 'Possible Unhandled Promise Rejection (id: 3):' and my code is not working properly. Image picker widget is not functioning.

It is also giving me some additional warnings like TypeError: Cannot read property 'launchImageLibrary' of null

i refereed it from a documentation https://instamobile.io/react-native-tutorials/react-native-aws-s3/ Here is my code:

App.js

import React, {useState} from 'react';
import {
  View,
  Text,
  TouchableOpacity,
  StyleSheet,
  Alert,
  Image,
} from 'react-native';
import {launchImageLibrary} from 'react-native-image-picker';
import Video from 'react-native-video';
function S3StorageUpload() {
  const [asset, setAsset] = useState(null);
  const selectFile = async () => {
    await launchImageLibrary({mediaType: 'mixed'}, result => {
      if (!result.assets) {
        Alert.alert(result.errorMessage);
        return;
      }
      setAsset(result.assets[0]);
    });
  };
  return (
    <View style={styles.container}>
      <TouchableOpacity onPress={selectFile}>
        <Text style={styles.button}>SELECT {asset ? 'ANOTHER' : ''} FILE</Text>
      </TouchableOpacity>
      {asset ? (
        asset.type.split('/')[0] === 'image' ? (
          <Image
            style={styles.selectedImage}
            source={{uri: asset?.uri ?? ''}}
          />
        ) : (
          <Video
            style={styles.selectedImage}
            source={{uri: asset?.uri ?? ''}}
          />
        )
      ) : null}
      {asset && (
        <>
          <TouchableOpacity onPress={() => setAsset(null)}>
            <Text style={styles.cancelButton}>Remove Selected Image</Text>
          </TouchableOpacity>
        </>
      )}
    </View>
  );
}
const styles = StyleSheet.create({
  button: {
    fontSize: 20,
    color: '#fff',
    backgroundColor: 'blue',
    paddingVertical: 20,
    paddingHorizontal: 30,
    marginHorizontal: 20,
    marginVertical: 10,
    textAlign: 'center',
    fontWeight: 'bold',
  },
  cancelButton: {
    backgroundColor: '#fff',
    color: 'blue',
  },
  selectedImage: {
    width: 175,
    height: 200,
    marginTop: 20,
  },
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
