Getting error "Node Key constraint requires Neo4j Enterprise Edition"

[rohankharwar]

Hi,

I am getting an error when trying to do a store copy on version 3.3.3 .

Node Key constraint requires Neo4j Enterprise Edition

Customer has constraints but we are not able to drop the constraint. Even after deleting the whole schema folder its not going away.

So we were trying to perform store copy to fix this issue. But the store copy if giving the following error.

./copy-store.sh enterprise /neo4jdb/data/databases/graph.db /neo4jdb/data/databases/fixed.db

I am able to reproduce this issue by loading some data and create a NodeKey constraint in the database and unique constraint.
Thanks,
Rohan

Any update on this we are getting the same issue

[InverseFalcon]

Still present for 3.5.11, in addition also getting similar messages when existence constraints are present.

@rohankharwar first you need to delete all the indexes.
