Gatsby builds only failing on Netlify

Hello, I’m building a complex site that pulls some data from git submodules and combines a bunch of data to ultimately pipe it into Gatsby. The issue is that I can get the builds to work absolutely fine on 2 separate Linux machines with different distros (Debian and Ubuntu), different Node versions (10.16 and 10.17), but somehow my builds are always broken on Netlify’s server. Does anyone know what I could do?

Repo : GitHub - 30-seconds/30-seconds-web at production (building from production branch)

Netlify log : Netlify App

Hi @Chalarangelo! While we can’t help with your source code in depth, this article describes how you can debug and some things you should try, especially around syncing versions between netlify and your local, and watching out for some things like case sensitive filesystems (I see some capital letters in your error: 6:25:35 PM: Snippet.html provided incorrect OutputType: 'Object({ resolve: [function resolve] })' that might be a contributing factor):

Take a look through there and hopefully you’ll find an answer. If not, you could try printing the error log after build, by using a build command like this:

npm run build ; cat /opt/buildhome/.npm/_logs/2019-*debug.log ; sleep 120 ; false

That will:

  1. run your build
  2. even if it fails, send the log file if it exists
  3. wait 2 minutes to finish logging that output file
  4. make sure we don’t publish a broken build.

You’ll have to undo that setting once you’ve understood and hopefully fixed the error since your site will never publish with that build command (you can restore to plain npm run build once fixed)
