No error specified in COMMIT callback when batching

[Bohdan Levchenko]

I do not specify callbacks to all queries in transaction cause it is possible to get aggregated result in commit callback. But as follow from code snippet it is not true for errors. Should errors be aggregated as well as results in commit callback?

db.batch(function(txn) {
    txn.query('MATCH n RETUUURN n', error => console.log(error)); // {code, message}
}, error => console.log(error)); // null
