I am having some difficulties with directives for FIELD_DEFINITION. I created a custom KotlinSchemaDirectiveWiring and set up hooks. I see that the KotlinSchemaDirectiveWiring.onField is called for the annotated fields. In onField I set a wrapped datafetcher, but that doesn't seem to be used.

[edwinRNDR]

Are there common pitfalls, am I missing steps?

Can you share a repo? Without code might be hard to guess what's missing in the setup.

[edwinRNDR]

I understand that, I will isolate the code tomorrow if the problem still persists. Meanwhile I found out that setting datafetchers only works for val fields and not for functions

[edwinRNDR]

So I guess I my expectations don't align with what can be done with directives?

[edwinRNDR]

what I am looking for is a way to indicate required user roles per field, also when they are a function

[Dariusz Kuc]

schema directive wiring should work on both properties and functions

see: https://github.com/ExpediaGroup/graphql-kotlin/blob/master/examples/server/spring-[…]up/graphql/examples/server/spring/query/CustomDirectiveQuery.kt and corresponding directives+wirings -> https://github.com/ExpediaGroup/graphql-kotlin/tree/master/examples/server/spring-[…]tlin/com/expediagroup/graphql/examples/server/spring/directives

[edwinRNDR]

ah yes, but it seems to work only if that function returns a primitive/scalar type?

[Dariusz Kuc]

should work regardless

[edwinRNDR]

ok, it clearly doesn't for me on version 4.2.0. I need some time to figure out what goes wrong
