StoreApi.objects.inserts returns: Connection closed before full header was received

[IbrahimYildirim]

Receiving this error in ~50% of the cases where i try to insert and object into my Google Cloud Storage bucket, so it's kind of a gamble of when it works and when it doesn't.

This comes when i call in my google_cloud_storage_service.dart.

      final resp = await storageApi.objects.insert(
        bucketObject,
        bucketName,
        uploadMedia: Media(file.openRead(), file.lengthSync()),
      );

The Exception and stacktrace of the error

ClientException: Connection closed before full header was received, uri=https://storage.googleapis.com/upload/storage/v1/b/[BUCKETNAME]/o?uploadType=multipart&alt=json
