FieldResults data producer returns schema mismatch for empty boolean value

Have you got a test that can recreate your problem?
I tried with this:

./web/modules/contrib/graphql_compose/tests/src/Functional/Core/EntityNodeTest.php

./vendor/bin/phpunit -c /app/web/core/ --stop-on-failure web/modules/contrib/graphql_compose/tests/src/Functional/Core/EntityNodeTest.php

  /**
   * Test unpublished node.
   */
  public function testUnpublished() {
    $this->node->setUnpublished();
    $this->node->save();

    $query = <<<GQL
      query {
        node(id: "{$this->node->uuid()}") {
          ... on NodeInterface {
            id
            status
            title
          }
        }
      }
    GQL;

    $content = $this->executeQuery($query);
    dump($content);
  }

And got back

1) Drupal\Tests\graphql_compose\Functional\Core\EntityNodeTest::testUnpublished
PHPUnit\Framework\Exception: array:1 [
  "data" => array:1 [
    "node" => array:3 [
      "id" => "d22b45e4-0e13-4c57-aecd-e894030c1915"
      "status" => false
      "title" => "Test"
    ]
  ]
]

Is your problem happening as a part of a larger query?

Let me see. It would need to happen in the RoutesTest.php I would guess since thats where we're seeing it.

Okay, i'm also unable to produce this issue on another site now and I think what we're seeing here is from another patch at https://www.drupal.org/project/graphql_compose/issues/3507357 🐛 Cannot return null for non-nullable field for Link Field in Paragraph Active so I'll modify that patch and I'm sure that will fix this issue and will close accordingly.
