### Bug
- Which version of SkyWalking, OS and JRE?
Skywalking 6.5.0, Debian 9, OpenJDK 1.8.0_212
- Which company or project?
Personal
- What happens?
I'm currently test driving Skywalking to get a feel of its capabilities and of OpenTracing.
I'm running Skywalking on my server, with a couple of applications.
As such, Skywalking has a minimal configuration (the same as the default, except the webapp.yml which has a user specified). It's still on H2.
I have a NPE related to GraphQL when one of the applications using the agent is sending metrics to the collector The NPE happens

Kindest regards!
Any pointers? Do I need to run a GraphQL server? Or do I have to disable some settings?
