Fly launch created docker-entrypoint.js - target is not defined

That looks like a bug, and I’d like to fix it. By any chance, are you using prisma, and can you share the datasource portion of your schame.prisma file?

A correct docker-entrypoint.js would look something like this:

github.com/fly-apps/dockerfile-node

test/base/litestream/docker-entrypoint.js

main

#!/usr/bin/env node

const { spawn } = require('node:child_process')
const path = require('node:path')
const fs = require('node:fs')

const env = { ...process.env }

;(async() => {
  // If running the web server then migrate existing database
  if (process.argv.slice(-3).join(' ') === 'npm run start') {
    // place Sqlite3 database on volume
    const source = path.resolve('./dev.db')
    const target = '/data/' + path.basename(source)
    if (!fs.existsSync(source) && fs.existsSync('/data')) fs.symlinkSync(target, source)
    const newDb = !fs.existsSync(target)
    if (newDb && process.env.BUCKET_NAME) {
      await exec(`litestream restore -config litestream.yml -if-replica-exists ${target}`)
    }

There will be a lot of variation on this theme, bases on things like if your app is "type": "module" or not.
