Detect absence of optional input fields

This is possible via a special argument, just like how the Context is a special argument.
You can in your resolver request the argument called Execution.Node and this will be provided just like how the Context is provided and it will not be exposed to your graphql schema.

You can see a simple sample here: https://github.com/aPureBase/KGraphQL/blob/main/kgraphql/src/test/kotlin/com/apurebase/kgraphql/integration/QueryTest.kt#L314

On the Execution.Node you have access to .getFields() and arguments and here you can find all information you need.

@jeggy Thank you very much.
That is exactly what i was looking for.

I was unable to find something like this in the documentation, so i assumed that it didn't exist.
It only lists Context as a possible option.
One suggestion could be to include a full list of all types that can be injected as parameters like this in the documentation.

This works for detecting which input fields a request has sent, but not if the request is using variables.
In that case, the input node is of type ValueNode.VariableNode and not ValueNode.ObjectValueNode.
Is there a way to gather the same information by resolving the VariableNode using the Execution.Node?
