`QuerydslDataFetcher.buildPredicate(…)` does not unwrap nested argument maps into fully-qualified property paths

[zeng-alt]

There is a problem with the QuerydsDataFetcher join query. Can I modify the QuerydsDataFetcher.getArgumentValues ​​method to fix it?

/**
* For a single argument that is a GraphQL input type, return the sub-map
* under the argument name, or otherwise the top-level argument map.
*/
@SuppressWarnings("unchecked")
private static Map<String, Object> getArgumentValues(DataFetchingEnvironment environment) {

This is my example repository： https://github.com/zeng-alt/graphql-test

This is my solution, but it's not very good：https://github.com/zeng-alt/zero-ddd/tree/master/zero-ddd-component/zero-ddd-graphql-component

This is indeed a bug on our side. We're storing incoming arguments in a map expecting keys of the map to represent full property paths. In this case (userInput: { name: "add", address: { country: "12" } }), the key address contains a nested map ({country=12}) that we're trying to bind to the address property.

What should happen is that we unwrap all nested maps and form an argument map with fully-qualified keys (address.country=12 instead of address={country=12}).
