NullPointerException when trying to record stream via the demo app

Hello,

I installed Web Call Server 5 from the AWS Marketplace for a trial. I have also added my own certificate via the JKS file to have HTTPS and WSS connections working. When testing the "Stream Recording" demo, the stream does not get saved to the recording folder (folder has not been changed from default config and seems to have all the required write permissions) - there is simply no recording file created in the target folder.

Checking the server logs I'm seeing a whole lot of the following exceptions in the flashphoner.log:

Code:
ERROR                    B - RTP-pool-29-thread-1 Caught exception on channel [id: 0x2f720c93, /172.31.0.166:31020].
java.lang.NullPointerException

As browsers I have been testing Chrome and Microsoft Edge on Windows 10, I can see my webcam and most of the other demo applications are working for me (i.e. I can stream and play live streams, snapshot also works, video chat and such all working)

Attached are the log entries when recording starts, just before the exceptions start occurring repeatedly.
