java.lang.NullPointerException in Jicofo log when starting a videobridge

Hi
I am seeing a Null Pointer exception everytime JVB is started.
The below is the config of the Jicofo and JVB on different servers, but when I tried with the JVB on the same servers as jicofo , the same issue occurs.
This issues seems to have been occurring ever since have enabled websockets.
Everything seems to work okay (including octo) despite this error.

If anyone could explain the error and how to get rid of it, would be great.
If it is a known issue and should be ignore that would be good to know too

Below are the configs and jifcofo, prosody and jvb logs

Anyone have any idea of this?
Thanks

any ideas ?

Are these latest stable versions?

Hi Damian,
The Prosody, jicofo and videobridge version that are installed are below

2021-04-26T12:32:37.567Z [modules/version/ComponentsVersions.js] Got xmpp version: Prosody(0.11.7,Linux)
Logger.js:154 2021-04-26T12:32:37.567Z [modules/version/ComponentsVersions.js] Got focus version: JiCoFo(1.0.644,Linux)
Logger.js:154 2021-04-26T12:32:37.812Z [modules/version/ComponentsVersions.js] Got videobridge version: 2.1.376-g9f12bfe2

You better update to the latest and see whether you repro again.

Hi Damian
We have now upgraded to the latest, but still see the same java exception
Everything seems okay despite the exception occurs upon starting up the videobridge

Can you attach the new exception logs …

Hi Damian

I have pasted below, the log of when jicofo starts (jicofo.log only) and when jvb starts (both jicofo.log and jvb.log)

Thanks

This is strange can you check your logging.properties file /etc/jitsi/jicofo/logging.properties
Maybe there is an error there that breaks stuff …

Thats the logging properties file

handlers=java.util.logging.ConsoleHandler
java.util.logging.ConsoleHandler.level=ALL
java.util.logging.ConsoleHandler.formatter=java.util.logging.SimpleFormatter
java.util.logging.SimpleFormatter.format=[%1$tc] %4$s %5$s%6$s%n
.level=DEBUG

I’ve changed level to INFO, so the Bad level value for property: .level has gone, but the exception still remains on starting a JVB

Updated log when changin level to INFO

That’s all in /etc/jitsi/jicofo/logging.properties, can you leave it empty to see whether that changes anything?

If I empty the file, there is no logging whatsoever
As mentioned, i got rid of the Bad level value for property by setting .level to INFO
