Impossible to update description by directive

[romash1408]

I am trying to somehow mark fields that have applied directive

@Component
class AuthDirective {
    @Bean
    fun authDirectiveWiring() = SchemaDirective("auth", AuthDirectiveWiring())

    inner class AuthDirectiveWiring : SchemaDirectiveWiring {
        override fun onField(environment: SchemaDirectiveWiringEnvironment<GraphQLFieldDefinition>): GraphQLFieldDefinition {
            val requiredScopes = environment.appliedDirective.getArgument("scopes").getValue<List<String>>()

            val field = environment.fieldDefinition

            // some logic with environment.codeRegistry.dataFetcher and scopes check

            val originalDescription = if (field.description.isNullOrBlank()) "" else "${field.description}\n\n"
            val description = "${originalDescription}@auth(${requiredScopes})"

            // transform rerturns new field definition with new description, but original definition in registry still has old description
            return field.transform {
                it.description(description)
            }
        }
    }
}

but later on this line my changed field definition is just thrown out
