Correct way to make a trigger, 1 out of 5 not fired?

[f1-outsourcing]

I was wondering if this the correct way to make a trigger

CALL apoc.trigger.add(
  'setCreatedProperty',
  'UNWIND $createdNodes AS n SET n.created = timestamp()',
  {phase: "afterAsync"}
)

Yesterday I accidentally noticed one of my test nodes does not have this created field.

╒═════════════════════════════════════════════╕
│n                                            │
╞═════════════════════════════════════════════╡

There is a bit of disclaimer here, as I am also testing with adding nodes through a plugin. But I guess on the other hand that should not be allowed to mess up this trigger behaviour.
