After adding Fastify and feh in your project, try this

import fastify from 'fastify';
import feh from '@zhaoworks/feh';

const server = fastify();

server.register(feh);

server.get('/', (_, reply) => {
  return reply.error(500, {
    message: 'something went completely wrong >:(',
  });

server.register(feh, {
  format: (status, error) => ({ error: error.message, our_fault: status === 500 })
});

server.get('/', (_, reply) => {
  return reply.error(500, { message: 'a cat must have bitten the wires' }); // -> { error: 'a cat must have bitten the wires', our_fault: true }
});
