Why the result are different between the excel function @TR and the EndPoint symbology/v1/lookup

Capture.JPGWhy does the Excel function "=@TR("NL0000000107";"TR.RIC";"Null=Blank")"
returns the RIC =.AEX

AND 

The EndPoint API Playground returns nothing when I run this URL?

https://api.refinitiv.com/discovery/symbology/v1/lookup

with body content:
{
  "from": [
    {
      "identifyTypes": [
        “ISIN”
      ],
      "values": [
        “NL0000000107”
      ]
    }
  ],
  "to": [
    {
      "identifyTypes": [
        “RIC”
      ]
    }
  ],
  "type": "auto"
}
