Through the API I am able to add Stock Components. Tried adding one with revision STANDAARD2 and get the same error: {"message":"VismaId: 282b14e4-36f5-4759-9da2-391ec9ccb7af. Error creating INKitSpecHdr. Object reference not set to an instance of an object."} POST https://integration.visma.net/API/controller/api/v1/KitSpecifications { "operation": "Insert", "kitInventoryID": { "value": "13.20.00.00.00" }, "revisionID": { "value": "STANDAARD2" }, "isActive": { "value": true }, "allowCompAddition": { "value": true }, "isNonStock": { "value": false }, "stockComponentLines": [ { "operation": "Insert", "compInventoryID": { "value": "13.22.32.15.00" }, "dfltCompQty": { "value": 9 } }, { "operation": "Insert", "compInventoryID": { "value": "13.24.50.75.00" }, "dfltCompQty": { "value": 7 } }, { "operation": "Insert", "compInventoryID": { "value": "14.30.35.00.80" }, "dfltCompQty": { "value": 150 } } ] }
