Steps to reproduce

Compare these two integration tests:

• StaticIncludeTrue_ShouldReturnProjectedRecordFields
• VariableIncludeTrue_ShouldReturnSameProjectedRecordFields

Both tests POST a GraphQL request to /graphql. The only relevant difference is the include directive on parent.child:

child @include(if: true) {
  records {
    id
    sequence
    label
  }
}

versus:

query Repro($includeChild: Boolean!) {
  parent {
    child @include(if: $includeChild) {
      records {
        id
        sequence
        label
      }
    }
  }
}

with variables:

{
  "includeChild": true
}

What is expected?

@include(if: true) and @include(if: $includeChild) with includeChild = true should produce the same selected payload.

The records response should include the explicitly selected scalar fields:

{
  "id": 1,
  "sequence": 7,
  "label": "alpha"
}

The variable-driven include should not alter the QueryContext<SampleRecord> selector for the nested records field when the directive evaluates to true.

What is actually happening?

The static include test passes, but the variable-driven include test fails.

The nested field is executed, and the correct record identity is present, but projected scalar fields are returned with default CLR values:

Assert.Equal() Failure: Values differ
Expected: 7
Actual:   0

Thanks for reporting this, I'll have a look :)

[tobias-tengler]

@faethto should be fixed with the next patch version (16.0.8).

Also again a big thanks for the detailed reproduction and issue! 🫡
