question

Hello, I can't create an offer for the DE marketplace in PRODUCTION environment. The same request for markeptplace_id EBAY_US works well in Production, despite all policies were created for DE market. Somehow this is only a problem in Production - it works well in Sandbox! Can you figure out what is causing the problem? I cannot post a request, because it is production environment. Response:

{
  "errors": [
    {
      "errorId": 25751,
      "domain": "API_INVENTORY",
      "subdomain": "Selling",
      "category": "REQUEST",
      "message": "A001 could not be found or is not available in the system for the marketplace EBAY_DE.",
      "parameters": [
        {
          "name": "text1",
          "value": "A001"
        },
        {
          "name": "text2",
          "value": "EBAY_DE"
        }
      ]
    }
  ]
}

Thank you.
