Zoho Desk Ticket Tags - Allowed Values

Zoho Desk Ticket Tags - Allowed Values

Hello,
I tried pushing tags to a ticket through the API endpoint "Associate Tag".
When I push the value "test" , it works, but when I push the value "Interesting" I get the following error message:
  2. {
  3. "response": {
  4. "statusCode": 422,
  5. "body": {
  6. "errorCode": "INVALID_DATA",

  14. ]

Could you please help me figure out which values are possible and which are not?

Thanks a lot for your help!
