java.lang.RuntimeException: Not set: com.bigdata.journal.IIndexManager Error when starting server from code

[mehalaga]

Hi, I am trying to start a server from code referring to https://github.com/blazegraph/database/blob/master/blazegraph-jar/src/main/java/com/bigdata/rdf/sail/webapp/StandaloneNanoSparqlServer.java
However, I am getting the java.lang.RuntimeException: Not set: com.bigdata.journal.IIndexManager error after executing StandaloneNanoSparqlServer.awaitServerStart(server).
indexManager parameter was set to null when creating a new instance of the StandaloneNanoSparqlServer.
