Incremental CSV import using "neo4j-admin" in Neo4j 5.x failed with below error

Command :

neo4j-admin database import incremental --force --skip-bad-entries-logging=false --skip-duplicate-nodes=true --max-off-heap-memory=95% --nodes="delta_node.csv" 

Error :

Import error: Couldn't find a matching index for (:asset {id})
Caused by:Couldn't find a matching index for (:asset {id})
java.lang.IllegalStateException: Couldn't find a matching index for (:asset {id}) 

Solution :

For incremental import, index for the property  is required . Without the index on the id property, the incremental import will be failed .

The best way to create an index is to create an uniqueness constraint for the id property.
