HelloWorld SW fails to start unless a "workflowdata" a field is passed in the input json

1) create an empty project with the most basic kogito deps for having SW. e.g. kogito-quarkus-serverless-workflow, etc.   2) Create hello-world.sw.json file with the content of the helloworld process in   https://github.com/serverlessworkflow/specification/blob/0.6.x/examples/README.md#Hello-World-Example   3) start the app with quarkus:dev   4) try to create an instance e.g. by using the swagger-ui   5) when the process starts the following exception is thrown. https://gist.github.com/wmedvede/db2645f5179ad45dd99f96f6538a82b5   some fragments here:           at org.jboss.threads.ThreadLocalResettingRunnable.run(ThreadLocalResettingRunnable.java:29)         at io.netty.util.concurrent.FastThreadLocalRunnable.run(FastThreadLocalRunnable.java:30)         at java.base/java.lang.Thread.run(Thread.java:834) Caused by: java.lang.NullPointerException         at org.kie.kogito.serverless.workflow.actions.InjectAction.execute(InjectAction.java:57)         at org.jbpm.workflow.instance.impl.NodeInstanceImpl.executeAction(NodeInstanceImpl.java:238)         ... 92 more   The expected behavior is that the process must start with no issues. Note:   By passing the following input  {"workflowdata":{}} , the process starts well, however it must start well in all cases.
