Query demands required parameter after version update

[QnavWhat]

Hi, I just updated from Version 6.3.0 to 6.6.0 and without changing the queries, I get the following error message when running GraphQL calls:

{"(400 Bad Request) query: Required parameter missing or invalid"}

The same query runs fine with the previous version and I could find any change log with related information. The higher versions I tested return this message as well. I get the error message for every query I tested like ''query MyQuery { shop { name } }". When using e.g. POSTMAN I can run the query without exception.

Thanks and regards

Hey @QnavWhat! Can you post the code you're using to send the query?

Hi @nozzlegear this is a code snippet to reproduce

Public Shared Function GraphQL_Query() As String

    Dim ret As String = ""

    Try
        Dim loc = ShopifyHelper2024.serviceLocation.ListAsync().Result.Items.First
        Console.WriteLine(loc.Id)

        Dim body = "query { shop { id name } }"
        Dim res = ShopifyHelper2024.serviceGraphQL.PostAsync(body:=body).Result
        ret = res("shop")("name")
        Console.WriteLine(ret)

    Catch ex As Exception
        ret = ex.Message
    End Try

    Return ret

End Function

The first call to serviceLocation is returning the location ID, which I just added to verify a correct initialisation of ShopifyHelper2024. Running the exact code with Version 6.4.0 will return Shop-Name but with Version 6.6.0 it will return error 400.

Is there anything I can try t to adapt in my API-call?

Hey @QnavWhat! Sorry, this slipped my mind. I’m currently making my way back home on a road trip so I can’t dig into any code. Can you try upgrading to the latest version of ShopifySharp to see if that fixes the problem?

I tried using Version 6.18.0 to see the output. However a different error appeared. So I ran through the Version to test where related changes happend:

6.4.0 --> fine with the code posted above 6.6.0-b118 --> {"(400 Bad Request) query: Required parameter missing or invalid"} 6.13.0-b182 --> {"Auf das verworfene Objekt kann nicht zugegriffen werden." & vbCrLf & "Objektname: ""System.Net.Http.StringContent""."} 6.18.0 --> still last error (which I guess relates to this issue https://github.com/nozzlegear/ShopifySharp/issues/1080)

Hey @nozzlegear , ist my latest post somehow helpful?

[nozzlegear]

@QnavWhat it is helpful, yes! I'm sorry, I've been utterly swamped. I've set aside time to look at this and other ShopifySharp issues later this evening.

[nozzlegear]

Good news! I've found the issue, it's one of the overloads in the GraphService, which I have an open pull request for. I'm working on it right now, I'll publish it either tonight or tomorrow and will let you know when it's ready to test.

[QnavWhat]

Awesome, thanks a lot :) Will test that asap after your publish
