fulfillmentTrackingInfoUpdateV2 Graph API request unable to parse the success response.

[iamSathishMohan]

I was using the below graph API request to update the fulfillment tracking info, eventhrough it produces the success response, the GraphService is unable to parse and failing with Expected StartObject token error for path $[0].extensions.value.

mutation fulfillmentTrackingInfoUpdateV2(
  $fulfillmentId: ID!
  $trackingInfoInput: FulfillmentTrackingInput!
  $notifyCustomer: Boolean
) {
  fulfillmentTrackingInfoUpdateV2(
    fulfillmentId: $fulfillmentId
    trackingInfoInput: $trackingInfoInput
    notifyCustomer: $notifyCustomer
  ) {
    fulfillment {
      id
      status
      trackingInfo {
        company
        number
        url
      }
    }
    userErrors {
      field
      message
    }
  }
}

The same query executes fine in postman

Hey, thanks for the report @iamSathishMohan! Could you show the C# code you're using to send this mutation? And can you confirm whether you're using ShopifySharp v6.22.0 or v6.22.1?

I am using the latest ShopifySharp. Found the error i made with the request and corrected it. But this still needs fix in ShopifySharp. The following error response in GraphQL is not processed and thorwing deserialization error.

{
    "errors": [
        {
            "message": "Variable $trackingInfoInput of type FulfillmentTrackingInput! was provided invalid value",
            "locations": [
                {
                    "line": 5,
                    "column": 3
                }
            ],
            "extensions": {
                "value": "{\"company\":\"Custom\",\"numbers\":[\"xxxxxxxxxxxx\",\"xxxxxxxxxxxx\"],\"urls\":[\"https://track.com/tracking/xxxxxxxxxxxx\",\"https://track.com/tracking/xxxxxxxxxxxx\"]}",
                "problems": [
                    {
                        "path": [],
                        "explanation": "Expected \"{\\\"company\\\":\\\"Custom\\\",\\\"numbers\\\":[\\\"xxxxxxxxxxxx\\\",\\\"xxxxxxxxxxxx\\\"],\\\"urls\\\":[\\\"https:\/\/track.com\/tracking\/xxxxxxxxxxxx\\\",\\\"https:\/\/track.com\/tracking\/xxxxxxxxxxxx\\\"]}\" to be a key-value object."
                    }
                ]
            }
        }
    ]
}

Ah I see the problem, thanks for copying that json! That helps a ton, I'll make sure this gets fixed.

---

Note for myself: the errors.extensions.value expects the type to be an object and it's converted to a C# IReadOnlyDictionary<string, object>, but in this json it's string.

Expected:

"extensions": {
  "value": { "foo": "bar" }
}

Actual

"extensions": {
  "value": "bar"
}
