I am using Expo with React Native for my app. upon clikcing on a button, i want the user to have the ability to upload multiple pdf files. I am using expo and the expo go app (on a physical device and on a simulator) to test code.

The issue now is that every time I want to open the Document Picker on IOS, I briefly see the document selector and then it disappears and I can’t pick any documents.

This is the code I use:

try {
      const result = await DocumentPicker.getDocumentAsync({
        type:'*/*',
        copyToCacheDirectory: true,
        multiple: false 
      });
      if (result.type === 'success') {
        console.log('Document picked:', result);
      } else {
        console.log('Document picking canceled');
      }
      console.log('result', JSON.stringify(result))
} catch (err) {
      console.log('error', err)
 
}

This is how my app.json file looks like:

    "name": "My name",

    },
    "plugins": [

      [

        {
          "iCloudContainerEnvironment": "Production"
        }
      ],
      [
        "expo-build-properties",
        {
          "ios": {
            "useFrameworks": "static",
            "deploymentTarget": "13.4"
          }
        }
      ]
    ],
    "extra": {
      "router": {
        "origin": false
      },
      "eas": {
        "projectId": "*********"
      }
    },
    "owner": "*********"
  }
}

I have followed the documentation to the best of my abilities and yet the document picker doesn’t work on a physical ios device or on a simulator.

Any help will be greatly appreciated.
