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

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

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

Then, how to stop it after checking all the file...
I don't want it to return msg[not found] after check every column.

because it return like this, if the data not found

it will return TypeError : Cannot read properties of undefined (reading 'ID')

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)
