Expected Behavior (Mandatory)

The relationship should be created.

Actual Behavior (Mandatory)

No relationships created.

Steps (Mandatory)

Create a rel with an end node withoud properties:

create (:Start {a: 1)-[:WORKS_FOR {id: 1}]->(:Project)

Execute this statement:

CALL apoc.export.cypher.all(null, {useOptimizations: { type: 'none'}, cypherFormat: 'create' })

Copy the cypherStatements result from above proc., delete and reimport entities:

CALL apoc.cypher.runMany(<cypherStatements>, {})

No rel. created.
