Unable to add label using Neo4j Rest API - Error reading as JSON '' - rest

Question

The neo4j rest api throws runtime exception (error reading as JSON '') when trying to add a label.
My current set up
<dependency>
<groupId>org.neo4j</groupId>
<artifactId>neo4j-rest-graphdb</artifactId>
<version>2.0.0</version>
</dependency>
<dependency>
<groupId>org.neo4j</groupId>
<artifactId>neo4j</artifactId>
<version>2.0.0</version>
</dependency>
<dependency>
<groupId>org.neo4j.app</groupId>
<artifactId>neo4j-server</artifactId>
<version>2.0.0</version>
</dependency>
Code that tries to create a new node and add a property and label. The runtime exception is thrown when we try to add the label. The rollback is working fine though. It appears that the API is trying to get details for the resource that is not yet created and trying to parse the response.
try ( Transaction tx = db.beginTx() ) {
//create new user
Node userNode = db.createNode();
userNode.setProperty( "id", id );
userNode.addLabel(DynamicLabel.label("GuestUser")); //throws runtime exception
tx.success();
}

Has anyone seen this problem so far.

Answer 1

This is a problem as those "pseudo" transactions only aggregate operations to send them at once at commit.
So you cannot do "read your writes" or make decisions on them.
And the addLabel operation uses the path returned from the structural info of the node which does not yet exist.
Don't think it's worth fixing. If you think so, please raise an issue at https://github.com/neo4j/java-rest-binding/issues
