Nullpointer Exception: instagram

[Babwenbiber]

From time to time, I get an exception on calling shareInstagramStory. The IG closes automatically and I get back to my app. Here Is the exception:

I am using social_share: ^2.1.1

Code

void shareOnInsta() async {
    await controller.capture().then((image) async {
      Directory tempDir = await getTemporaryDirectory();
      String filePath = '${tempDir.path}/my_image.jpg';
      File(filePath).writeAsBytes(image);
      SocialShare.shareInstagramStory(
        filePath,
        attributionURL: "https://deep-link-url",
      ).then((data) {
        print(data);
      });
    }).catchError((onError) {
      print(onError);
    });
  }
