Its hard to know without the source code. Usually this is caused by a dynamic require.

You can check in /Users/seepine/workspace/test-transfer/dist/worker1.js for something like require(str) and change it to require('./indexes') perhaps.

ncc build app.ts -o dist

Hi, try index.ts

import fastify from "fastify";
const server = fastify({});

server.listen({
  host: "0.0.0.0",
  port: 3000
});

pnpm i fastify
pnpm i @vercel/ncc -D

Add scripts to package.json

"ncc": "ncc build index.ts -o dist-ncc"

And run

pnpm ncc
