Hi @sorensenjg

First I would like to thank you for your work on this package.
As the thread says, I wanted to ask wether it is possible to add support for the conditions set on the WP dashboard?

@sorensenjg Is there a way to query cross-sell products for composite products? I am trying to query both up-sell and cross-sell products but only found up-sell.

Problem

When querying a product by uri using the nodeByUri query, if the product is a "composite" product, there is an error returned:

Abstract type UniformResourceIdentifiable must resolve to an Object type at runtime for field RootQuery.nodeByUri with value "instance of WPGraphQL\WooCommerce\Model\Product", received "Product". Either the UniformResourceIdentifiable type should provide a "resolveType" function or each possible type should provide an "isTypeOf" function.

For example, I have a composite product with the uri: /product/battery-operated-rs/

If I run the following query:

{
  nodeByUri(uri: "/product/battery-operated-rs/") {
    uri
  }
}

I get the following response:

{
  "errors": [
    {
      "debugMessage": "Abstract type UniformResourceIdentifiable must resolve to an Object type at runtime for field RootQuery.nodeByUri with value \"instance of WPGraphQL\\WooCommerce\\Model\\Product\", received \"Product\". Either the UniformResourceIdentifiable type should provide a \"resolveType\" function or each possible type should provide an \"isTypeOf\" function.",
      "message": "Internal server error",
      "extensions": {
        "category": "internal"
      },
      "locations": [
        {
          "line": 2,
          "column": 3
        }
      ],
      "path": [
        "nodeByUri"
      ],
      ...

Resolution

I was able (with the help of @kidunot89) to resolve this with the following filter:

add_filter( 'graphql_interface_resolve_type', function( $type, $node, $interface ) {
  switch( true ) {
    case is_a( $node, '\WPGraphQL\WooCommerce\Model\Product' ) && 'composite' === $node->type:
      $type = 'CompositeProduct';
      break;
  }
  return $type;	
}, 10, 3 );

And with this filter in place, I can successfully query a composite product and get it back as expected:

I believe this filter should live within this plugin as this plugin is the bridge between WooGraphQL and Composite products
