Gatsby build - failed Building production JavaScript and CSS bundles

hi there, sorry to be slow to get back to you!

so you have a warning a little further up in your build log but that isn’t the reason why it’s failing - it is definitely this section that is causing problems.

First question is always: does it build locally?

I’m not 100% sure what is causing this behaviour but some basic troubleshooting can be found:

This Support Guide contains a ton of useful debugging tips that can likely help you solve your problem :slight_smile:

If that doesn’t help, let us know, and we’ll dig a bit more.
