Introspection with standard values does not work

[ZirgVoice]

When using the default value, introspection does not work.
For the ID scalar, I get the error Serialize expected type ID but got Map.
For Bool, the error is Cannot convert value to AST: 0.
For Int, Cannot convert value to AST: 1.
This is what I managed to check. Bool definitely worked before update 2.10.1 - Paramaribo

Hey, this is interesting. Are you declaring the type as Swift's Bool or GraphQLBool like done in the test here? https://github.com/GraphQLSwift/GraphQL/blob/main/Tests/GraphQLTests/TypeTests/IntrospectionTests.swift#L40

[ZirgVoice]

No, I do it like this

class Schema: PartialSchema<GraphQLResolver, Context> {

    // MARK: - Query
    @FieldDefinitions
    override var query: Fields {
        Field("raceSession", at: GraphQLResolver.raceSession) {
            Argument("restart", at: \.restart).defaultValue(false)
        }
    }
}

I tried to recreate this issue in Graphiti on this branch, see this commit, but wasn't able to. The test runs successfully.

Could you edit this test or create a new one reproducing the errors you are seeing?

I'll try to reproduce this issue in a test later and will let you know.

I noticed that you're calling the query in the tests, but the problem is not with them. The error is in the response to the introspection query. Here’s an example of the call
This is a POST request

{"query":"\n    query IntrospectionQuery {\n      __schema {\n        \n        queryType { name }\n        mutationType { name }\n        subscriptionType { name }\n        types {\n          ...FullType\n        }\n        directives {\n          name\n          description\n          \n          locations\n          args {\n            ...InputValue\n          }\n        }\n      }\n    }\n\n    fragment FullType on __Type {\n      kind\n      name\n      description\n      \n      fields(includeDeprecated: true) {\n        name\n        description\n        args {\n          ...InputValue\n        }\n        type {\n          ...TypeRef\n        }\n        isDeprecated\n        deprecationReason\n      }\n      inputFields {\n        ...InputValue\n      }\n      interfaces {\n        ...TypeRef\n      }\n      enumValues(includeDeprecated: true) {\n        name\n        description\n        isDeprecated\n        deprecationReason\n      }\n      possibleTypes {\n        ...TypeRef\n      }\n    }\n\n    fragment InputValue on __InputValue {\n      name\n      description\n      type { ...TypeRef }\n      defaultValue\n      \n      \n    }\n\n    fragment TypeRef on __Type {\n      kind\n      name\n      ofType {\n        kind\n        name\n        ofType {\n          kind\n          name\n          ofType {\n            kind\n            name\n            ofType {\n              kind\n              name\n              ofType {\n                kind\n                name\n                ofType {\n                  kind\n                  name\n                  ofType {\n                    kind\n                    name\n                  }\n                }\n              }\n            }\n          }\n        }\n      }\n    }\n  ","operationName":"IntrospectionQuery"}

At the end of the response to this call, there is an error

                }
            ]
        }
    },
    "errors": [
        {
            "message": "Cannot convert value to AST: 0",
            "path": []
        }
    ]
}

Here in tests I reproduced the error: ZirgVoice/Graphiti@d789f07

The error is in the response to the introspection query

Oh duh, I was able to recreate in my tests by making the introspection query.

Alright, I believe this is related to the serialization of the standard GraphQL Scalar types. I've got a fix here that resolves my reproducer (I haven't added tests yet): https://github.com/NeedleInAJayStack/GraphQL/commits/fix/issue-152/

This should now be fixed in 2.10.2
