Hi there,
Could someone please explain why I’m getting null pointer exceptions?
I’m using spring data neo4j and trying to marshal a node using
createEntityFromStoredType. In my tests it works, but in the production code
it fails with a null pointer… not at all sure why - very confusing!
def result = ee.execute(“match (b) return b)
result.columnAs('b').collect { def n ->
neo4jTemplate.createEntityFromStoredType(n, null)
}
In my test code it returns a list of nodes correctly mapped, but in my
production code I’m getting:
[Assertion failed] - this argument is required; it must not be null. Stacktrace
follows:
Message: [Assertion failed] - this argument is required; it must not be null
Line | Method
->> 30 | doCall in
db.repositories.SearchGraphService$_getLocatedObjectsOfType_closure2
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
| 23 | getLocatedObjectsOfType in
db.repositories.SearchGraphService$$EP5V0ixU
Where the createEntityFromStoredType is on line 23.
The spring wiring in both cases looks identical, and so I presume that any
mappers are auto wired correctly.
Been scratching my head for hours! Could really do with a hand! :)
Thanks,
Joe
