Here is a much better, more modern way and avoids the risk of an infinite loop.

```javascript
const entry = msg.payload.find(e=>e.ID == "D20A485C")

if (entry) {
  msg.payload = { "NAME" : entry.NAME };
  return msg
}

```

Difficult to tell from a screenshot an no sample data.

Can you select the bunch of related nodes & export the flow (CTRL+E) and paste the copied flow into a code block.  
I will also need some sample data of the CSV (it can be fake but must be correct format)
