我正在尝试创建一个移动应用程序并使用AWS位置跟踪器。我有以下代码：

import React from 'react';
import AWS from 'aws-sdk/dist/aws-sdk-react-native';

export default function App() {
  const client = new AWS.Location({
    region: 'eu-west1',
    credentials: {
         ...
    }
  })
  return (
    <View style={styles.container}>
      <Text> Altitude</Text>
    </View>
  );
}
const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: '#fff',
    alignItems: 'center',
    justifyContent: 'center',
  },
});

我遇到了一个我以前从未遇到过的致命错误。
