synchronization fails

 

We are trying to update the following products, that we know exists in the shop, since we are getting the variant id’s from a 1 minute earlier request.

{

   "setFiniteOperations":[

      {

         "variantId":"f8a537ec-6b0d-43d5-8925-74791dc77517",

         "quantity":30

      },

      {

         "variantId":"2bea2a40-d84f-4f11-ab7a-523cc8cc0709",

         "quantity":16

      },

      {

         "variantId":"40d444b1-1048-43e4-a1a6-fe66ba23d0e2",

         "quantity":26

      },

      {

         "variantId":"b3acd1d0-2931-46c6-ac89-5a406f9634b5",

         "quantity":28

      },

      {

         "variantId":"a8dbb2a5-c9d2-4846-9334-f9abc4c7e909",

         "quantity":8

      },

      {

         "variantId":"c8db7479-d675-460e-881a-5a7f48318d1a",

         "quantity":0

      },

      {

         "variantId":"6eabadc8-8671-4f75-8f98-d0756bf0c15c",

         "quantity":0

      },

      {

         "variantId":"22798ca7-04b6-4e9a-a4c3-1727a2e90795",

         "quantity":31

      },

      {

         "variantId":"ff34993a-0b01-4278-bdfc-5a8f2f20120f",

         "quantity":4

      },

      {

         "variantId":"422c1e4b-9dd8-4558-a0b6-906a0549045b",

         "quantity":25

      }

   ]

}

 

When doing that we get the following error:

 

{

  "type" : "INVALID_REQUEST_ERROR",

  "subtype" : "INVENTORY_ITEM_NOT_FOUND",

  "message" : "One or more inventory items specified in the request were not found.",

  "details" : null,

  "contextId" : "EWSPROWWAVAMUSPLAYSP"

}

 

Any idea of what is wrong?

 

Help much appreciated
