could you please post versions of:

• Neo4j (incl whether it's Community or Enterprise)
• GraphAware Framework
• Neo4j expire

Thanks!

[lyfxmw]

i think i ask wrong question。。
Does GraphAware have to set the time to live of nodes and relationships at the same time?

The above problem is only set the node。

versions:
Neo4j 3.4.6
GraphAware Framework:community-all-3.4.6.52
Neo4j expire:3.4.6.52.4

case 1： only start nodeTtl nodeExpirationStrategy choose orphan
When nodes is deleted, transactions may not be committed...

neo4j can't delete anyone by cypher statement latter
it throw this error：Neo.ClientError.Transaction.TransactionHookFailed

case 2：only start nodeTtl nodeExpirationStrategy choose force

when time is up，
neo4j loop reports the following error：
Task execution threw an exception: Transaction was marked as successful, but unable to commit transaction so rolled back. Transaction was marked as successful, but unable to commit transaction so rolled back.
