"stock_on_hand" field for Item is not saving on create/update via API

I have tried to create/update zoho Item via API, all fields beside "stock_on_hand" are saved/updated correctly, but "stock_on_hand" is not saving in any way. The simplest json for this can be:
  1. {
  2. "name": "Test",
  3. "stock_on_hand": 25
  4. }
      or
      
  1. {
  2. "name": "Test",
  3. "stock_on_hand": "25"
  4. }
I have tried both with string and number format for 'stock_on_hand' field. I am not getting any errors, evertying is being saved and updated, excluding exactly that field.
