Description

In hop 2.2.0-SNAPSHOT, storing execution information in neo4j enables "Execution lineage" tab in the "execution information" perspective.
When a root workflow is opened, clicking in the "Execution lineage" tab displays nothing and a exception is raised, visible in the console.
In Hop Web it also kills the application causing restart.
No error is raised in case of child wf/pl.

Error in Hop GUI console:
