[Next.js] Internal error during "Functions bundling" on Build

Site name: friendly-mcnulty-040c07

Build log: Netlify App


It works perfectly on my localhost, but I’m new to netlify and i don’t know if I’m missing something.

Hi @glantucan

Your build log is private (because your repository is) so cannot see the error. Is it the same as posted in NextJs Deployment Issue?

Hi, coelmay. I tried to follow up on that thread because it seems a similar issue. But somehow my post didn’t get published, maybe because I just had signed in into the forum and I didn’t have yet that permission.

Anyway, here it is the log

Thanks for posting your log @glantucan. Indeed you are receiving the same error as @utdev.

Error: readdirp: root argument is required. Usage: readdirp(root, options)

This is also the same error received by @robhicks (see: Node version not being set using .nvmrc in root of monorepo or as NODE_VERSION envar) though using SvelteKit not Next.js. @hrishikesh has posted some potential solutions you might like to try (though not sure it is entirely solved yet.)

The common element through all three is

readdirp (/opt/buildhome/.netlify-build-nvm/versions/node/v12.16.3/lib/node_modules/@netlify/build/node_modules/readdirp/index.js:262:11)

Hopefully a Support Engineer will have more information on this issue soon. Hang tight.

Thanks @coelmay. I’m shooting blind here, but how is it the node version on that log trace seems to be 12.16.3?
Shouldn’t be 16.8.0? as per

8:29:07 AM: Now using node v16.8.0 (npm v7.21.0)

I don’t know the full ins-and-outs, but it appears the function bundling is done with a different node.js version. Whether by design, necessity, or otherwise I cannot say.

Funny, I tried to use esbuild for the functions as @hrishikesh suggested on the other thread
netlify.toml

[build]
  command = "npm run build"
  publish = "out"
[functions]
  node_bundler = "esbuild"

And now I get some extra error messages:

Which makes no sense because I already had that issue on my local environment and it seemed to solve when I did what it suggests on my next.config.js:

module.exports = {
  reactStrictMode: true,
  target: "serverless", // Apparently this is required by Netlify
  webpack5: true, 
  webpack: (config, { webpack, isServer}) => {
    config.externals = config.externals.concat([
'mssql', 'mysql2', 'oracle', 'oracledb', 'postgres', 'redshift', 'sqlite3', 'pg', 'pg-query-stream', 'tedious']);
    return config;
  },
}

Ops! I managed to make it work!! :smile:

I don’t remember where did I get this idea from, but added this extra bit ({ knex: 'commonjs knex' } ) to the externals :

config.externals = config.externals.concat(['mssql', 'mysql2', 'oracle', 'oracledb', 'postgres', 'redshift', 'sqlite3', 'pg', 'pg-query-stream', 'tedious', 
      { knex: 'commonjs knex' } ]);

And suddenly the build no longer fails.

It says this though:

9:51:08 AM: ❯ The following Node.js modules use dynamic expressions to include files:
9:51:08 AM:    - sharp
9:51:08 AM:    - knex
9:51:08 AM:    - @ampproject/toolbox-optimizer
9:51:08 AM: ​
9:51:08 AM:   Because files included with dynamic expressions aren't bundled with your serverless functions by default,
  this may result in an error when invoking a function. To resolve this error, you can mark these Node.js
9:51:08 AM:   modules as external in the [functions] section of your `netlify.toml` configuration file:
9:51:08 AM: ​
9:51:08 AM:   [functions]
9:51:08 AM:     external_node_modules = ["sharp", "knex", "@ampproject/toolbox-optimizer"]

I don’t know about ‘sharp’ and ‘@ampproject/toolbox-optimizer’, I didn’t include them explicitly, I guess they are dependencies of some other module.

I don’t know what dynamic expressions exactly mean. I don’t think I’m using them. I just use require() to import knex in a simple module get a database connection:

var knex = require('knex');
var knexConf = {
  client: 'mysql',
  connection: {
    host : process.env.CMS_DB_HOST,
    port: process.env.CMS_DB_PORT,
    user : process.env.CMS_DB_USER,
    password : process.env.CMS_DB_PASS,
    database : process.env.CMS_DB_DB
  }
};
var drupalDB;

export default function getDrupalDB () {
  if (drupalDB) {
    return drupalDB;
  }
  drupalDB = knex(knexConf);
  return drupalDB;
}

and then have other simple modules to perform the queries (needed for my getStaticProps() and getStaticPaths() functions) which have the following structure:

import getDrupalDB from './drupalDb';
var videosCache;
export default async function getAllVideos() {
  if (videosCache) {
    return videosCache;
  } else {
    var drupalDB = getDrupalDB();
    var videosQuery = drupalDB.from('node') ... ; // complex query expression here
    videosCache = await videosQuery;
    return videosCache;
  }
}

Am I doing something wrong or is it the knex module?

Do you maybe recommend some other module to connect to a mariaDb database? I like the knex syntax and features, but I don’t like that it’s giving me so many troubles. It hurts my trust on it seriously. Maybe because I don’t really understand what the problem is.

This is part of some tests we are doing before migrating our rockalingua.com site. We have a lot of customers and we really need this to work flawlessly.

While I’m not sure about the library,

this would mean that you’re trying to load a file from the file-system (not a module) dynamically. It might be in an if/else block or something else. You should try to require the files regardless or whether they would be used or not. You can try something like:

Sorry for my late response, this week has been really busy.

I’m not sure I understand. Those modules may be doing what you say internally, but they are not mine. I imported ‘knex’ explicitly to access and query the database. The other two must be imported by other third party modules I used because I don’t have any explicit import or require pointing to them.

What happens when you add that line to your netlify.toml?
