bull-board: Bull Board UI stuck on "Loading"

Hi, we have been looking for something to monitor our Bull Queues for quite some time. and I use Bull Board for monitor queues, I’m using Fastift rather than Express, and I have been stuck on Loading… This happened only on production, but on development all going well.

Reproduce:

export const setupBullBoard = (app: NestFastifyApplication) => {
  const bullServerAdapter = new BullFastifyAdapter();
  bullServerAdapter.setBasePath('/queues/ui');

  const queues = Object.values(QUEUES).map(
    (queue) => new BullAdapter(new Queue(queue)),
  );

  createBullBoard({
    queues,
    serverAdapter: bullServerAdapter,
  });

  app.register(bullServerAdapter.registerPlugin(), {
    prefix: '/queues/ui',
    basePath: '',
  });
};

“bull”: “^4.2.1” “@nestjs/core”: “^8.2.5” “@bull-board/fastify”: “^3.9.0”
