Nullpointer Exception in JCypher when connecting with Neo4j 3.0.1 #22

Closed wouterd closed 8 years ago

wouterd commented 8 years ago

Neo4J version: 3.0.1 JCypher version: 3.4.0

When trying to get errors from a queryresult, the JCypher library throws an NPE. I'm trying to investigate, but maybe you have an idea already? :)

Sorry, but JCypher is currently not ready for Neo4J 3.x The August release (3.5.0) is planned to support Neo4J 3.x.

best regards, Wolfgang

Thanks for the info, we'll downgrade. :)

JCypher has been tested against Neo4J 2.3.2 :)
