PlatformException with release version

I'm seeing the following error in logcat when testing a release version of my APK. Everything works fine when the APK is a debug version.

Flutter version: v1.17.0 aws_s3 version: ^0.1.1+hotfix.5 Device: OnePlus 6, Android 10

Has anyone else experienced this? Happy to provide more information/code if necessary.

Usage:

Future<void> uploadVideo() async {
    final Directory extDir = await getApplicationDocumentsDirectory();
    final String filePath = '${extDir.path}/xxx.mp4';

    AwsS3 awsS3 = AwsS3(
      awsFolderPath: "xxx",
      file: File(filePath),
      fileNameWithExt: "xxx.mp4",
      poolId: "xxx",
      region: Regions.EU_WEST_1,
      bucketName: "xxx"
    );

      String result = await awsS3.uploadFile;
      debugPrint(result);
  }
