applyResolversEnhanceMap 不向解析器添加自定义装饰器？

Question

我正在使用 typegraphql-prisma 包，并试图将自定义装饰器应用于我生成的解析器，但无济于事。我正试图绕过瓶颈，但似乎无法识别它。

// src/lib/enhance.ts
export const mapped: ResolversEnhanceMap = {
  Like: {
    deleteLike: [RateLimitMiddleware()],
    createLike: [RateLimitMiddleware()],
  },
};

// src/lib/middleware.ts
const duration = 60 * 60;
const limit = 1;

export function RateLimitMiddleware() {
  console.log("Middleware is running...");
  // nothing below this line runs
  return createMethodDecorator<Context>(async ({ context, info }, next) => {
    const key = `rate-limit:${info.fieldName}:${context.user.user.id}`;
    console.log(key);
    const total = await redis.incr(key);
    if (total > limit) {
      throw new Error("You are being rate limited.");
    } else if (total === 1) {
      await redis.expire(key, duration);
    }
    return next();
  });
}

// src/index.ts
const app = express();
const http = createServer(app);
const schema = await buildSchema({
  resolvers: [...resolvers, AuthResolver, ImageResolver, CardResolver],
  validate: false,
});

applyResolversEnhanceMap(mapped);
// ... more code here

我的 RateLimit 装饰器似乎根本没有被应用？每个请求都会触发 console.log 中的任何一个。我错过了什么？

对于遇到同样问题的任何人：答案是在 buildSchema 之前致电 applyResolversEnhanceMap。
