Я пытаюсь добавить директивы в наш API GraphQL и следую этому примеру, https://www.apollographql.com/docs/apollo-server/features/creating-directives.html#Uppercasing-strings, однако я получаю сообщение об ошибке сервера (без директивы сервер работает!):
** Uncaught Error: Duplicate schema type name Integer **

Схема очень большая, поэтому я не могу опубликовать ее здесь, однако тип схемы 'Integer' не был продублирован. Я следовал нескольким различным руководствам, но продолжаю сталкиваться с этой ошибкой.
Мы используем Apollo Server 2.1.0 и GraphQL 14.0.2
Настройка сервера:
class error_extension extends GraphQLExtension {
willSendResponse(o) {
const { context, graphqlResponse } = o;
context.add_additional_error_reporting(graphqlResponse.errors);
return o;
}
}
// Create (or import) a custom schema directive
class UpperCaseDirective extends SchemaDirectiveVisitor {
visitFieldDefinition(field) {
const { resolve = defaultFieldResolver } = field;
field.resolve = async function (...args) {
const result = await resolve.apply(this, args);
if (typeof result === 'string') {
return result.toUpperCase();
}
return result;
};
}
}
// Server settings
const server = new ApolloServer({
typeDefs,
resolvers,
schemaDirectives: {
upper: UpperCaseDirective,
},
context: async ({ req, res }) => {
// some auth logic here - removed for the purpose of this
return {
add_additional_error_reporting(errors) {
if (!errors) return;
errors = errors.map(item => {
// add request data to the returned error
if (`extensions` in item && item.extensions !== undefined)
item.extensions.request_details = req.body;
return item;
});
return errors;
},
req,
res
};
},
