Map Matching problem with tunnels

Tunnels are always a problem for GPS devices. Usually there is no GPS information (track points) about trajectory parts within tunnels available. The Map Matcher has to route in those cases from one tunnel's end to the other.
In some situations GPS track points at the end of a tunnel are too erroneous so routing fails and skips the way segments representing the tunnel, resulting in gaps of the map matched path.

NullPointerException when setting state to ACTIVE

I am trying to follow the configurations instructions but am getting stuck when trying to set the state of the imported map. The following request results in a null pointer exception.

curl -X PUT "http://localhost:7474/graphium/metadata/graphs/osm/versions/1/state/ACTIVE"

08:04:24,250 ERROR [GlobalExceptionController.handleInconsistentStateException()]  Error occured during request

I am running neo4j in a docker container, and mounting the build plugins to the correct directory.

docker run -d -p 7474:7474 -p 7687:7687 -v ${PWD}/plugins:/var/lib/neo4j/plugins -v ${PWD}/conf:/var/lib/neo4j/conf --name neo4j neo4j:3.2.3

The issue seems to be with the metadata being passed the observable, but I can't say for sure.
