Michael -
I have trimmed my node object
{ name: 'shekar',
email: '[email protected]',
friends: undefined,
payload: 'null',
type: 'user' }
I am not sure why the merge statement is being interpreted as an array.
Here is how I am constructing the merge statement
var cypherQuery='MERGE (user:Person ' + node + ') ON CREATE SET
user.created = timestamp() ON MATCH SET user.lastSeen = timestamp() RETURN
user';
and the resulting cypher is ..
"MERGE (user:Person [object Object]) ON CREATE SET user.created =
timestamp() ON MATCH SET user.lastSeen = timestamp() RETURN user"
