I need to import a big JSON file in Neo4J.
Because it should be quite fast I wanted to use apoc.periodic.iterate

My Approach is the following

    CALL apoc.periodic.iterate(
  "CALL apoc.load.json('sampled.json') YIELD value RETURN value",
  "UNWIND value.authors AS author
WITH author
WHERE author.id <> '' AND author.name <> '' |
     MERGE (a:Author {id:author.id})
     ON CREATE SET a.name = author.name
   )",
  {batchSize:1000, parallel:false}
)

But this throws the following Error:

(line 3, column 45 (offset: 142))rn"WHERE author.id <> '' AND author.name <> '' |"rn                                             ^": 31
}

I can’t figure out what the problem is and how to fix it.
