I executed this query
Neo4j 4.2.3
Neo4j Browser 4.2.5
CALL apoc.load.csv('file:///bonsai/client_id_geo_map.csv',{nullValues:['(not set)','']}) YIELD map
MATCH (j:Journey {customerID: map.client_id, date: reverse(split(map.date,'/'))[0] + '-' + reverse(split(map.date,'/'))[1] + '-' + reverse(split(map.date,'/'))[2]})
RETURN j
It gave me this error : Neo.DatabaseError.Statement.ExecutionFailed
Without any more information, the error field itself under the error is empty. With all due respect to the awesome neo4j developers, WTF I'm suppose to do with that lol.
