Getting error 500 when using expo-document-picker

Question

I am using Document Picker (Expo) . Just writing the simple code but it is throwing me error of 500 , i don't understand why it is throwing me this error .

The code library i m using is -> expo install expo-document-picker .

import * as DocumentPicker from 'expo-document-picker';

  const _pickDocument = async() =>{
    let result = await DocumentPicker.getDocumentAsync({});
    alert(result);
    console.log(result);
  }

<>
 <Button title="Select Document" onPress={_pickDocument} />
</>

It is the code which i m using in my project

Error showing in console ->
