Hi, trying to perform some batch MERGEs in Neo4j Enterprise 3.5.5, I get the following error Message, what does that mean?
Neo.DatabaseError.Statement.ExecutionFailed: Uh oh... There was no slot for ` w2@451`
The cypher part
WITH w, word1, word2
MERGE (w1:Word {searchterm:tolower(word1)})
ON CREATE SET w1.name=word1, w1.count = 1
ON MATCH SET w1.count = w1.count + 1
MERGE (w1)-[r1:PART_OF]->(w)
MERGE (w2:Word {searchterm:tolower(word2)})
ON CREATE SET w2.name=word2, w2.count = 1
ON MATCH SET w2.count = w2.count + 1
MERGE (w2)-[r2:PART_OF]->(w)
MERGE (w1)-[r3:NEXT]->(w2)
It should merge nodes for some words (word1/word2) which are part of a baseword (w). The size of the initial WITH is about 9000 lines, where w is a node reference and word1/word2 are strings.

Edit:
Same problem with just 6 lines. But it works without the ON CREATE SET and ON MATCH SET lines (... but I need them)
