I hope working around the issue is not causing inconvenience to you.
We have logged an item in our backlog and will further look into the matter. Based on the current information from the StackOverflow thread and the GitHub issue we can not draw a definitive conclusion where the problem is. Yet if we determine that the exception is caused by our product we will deploy a fix with one of our future releases.
If you have any other questions or face further difficulties please get back to us.
