I posted this on the GitHub issues for the tool but haven't got any responses, so figured it wouldn't hurt to post it here as well.
I am running the Neo4j Desktop v1.2.1 and Neo4j ETL Tool v1.4.2 on a Windows 10 machine. I have a remote instance of Neo4j running on a Linux machine (Neo4j v3.5.6) and I have a dB2 database running on an IBM i machine.
I am using a JDBC to connect to the dB2 database and 'Test Connection' results in success (though it does appear to register my username as the schema, even though I am specifying a default schema that is not my username) I am trying to use the ETL tool to map metadata and though the connection appears to be successful, the output (in the logs) is empty. I have attached a picture of my JDBC setup and the resulting logs (when I hit 'Start Mapping'). Any help or tips or questions for more information would be appreciated!
