Unable to fetch SaleOrders

Unable to fetch SaleOrders

We are trying access SalesOrders on the new API, but we keep receiving the following error.  We are using Postman to test.

Error:
  1. {
  2.     "code": "INVALID_MODULE",
  3.     "details": {},
  4.     "message": "the module name given seems to be invalid",
  5.     "status": "error"
  6. }
The scope for the access token is: ZohoCRM.modules.ALL

When we duplicate the Postman tab and query for Accounts or Contacts, we get successful results.  Is there a setting on the CRM we need to turn on?

Thank you.
