Null Pointer exception

[Jaimin19parmar]

Hii everyone,
When I am trying to onboard the new server then I got a null pointer exception.
Exception in thread "Thread-28" java.lang.NullPointerException at java.util.Objects.requireNonNull(Objects.java:203) at java.util.Arrays$ArrayList.<init>(Arrays.java:3813) at java.util.Arrays.asList(Arrays.java:3800) at org.openconnectivity.otgc.domain.model.resource.secure.doxm.OcDoxm.parseOCRepresentation(OcDoxm.java:130) at org.openconnectivity.otgc.data.repository.DoxsRepository.lambda$null$5(DoxsRepository.java:129)
Otgc-linux = 3.0.0
System= Ubuntu 20.04

Let me know the possible cause and its solution.
Thanks :).

Hello,
OTGC Linux v3.0.0 has been fully tested with Ubuntu 16.04 and 18.04. Please, try to make a clean installation on that system version and let us know if you still face that exception.
