Steps to Reproduce

  1. Create a simple fastify api example
  2. Change the logger to @fastify/one-line-logger

Expected Behavior

The fastify api will deploy successfully on vercel

I don't think the pino transport system would work on vercel. You should use it as a stream: https://github.com/pinojs/pino-pretty?tab=readme-ov-file#usage-as-a-stream.

Use pino-pretty as a stream worked, here is the code:

import Fastify from 'fastify';
import pino from 'pino';
import pretty from 'pino-pretty';
const stream = pretty({
  translateTime: 'SYS:HH:MM:ss Z',
  messageFormat: '{msg} {req.method} {req.url}',
  include: 'time,pid,level',
  hideObject: true,
  colorize: false,
});
const logger = pino({ level: 'info' }, stream);

const app = Fastify({ logger });
