Expected behavior

What should happen?

Steps to reproduce

1. This is the branch on github

2. Running dev:css and dev:site works fine and the site looks how it should.

3. Running build generates the error listed above. The issue started with commit c687dcbbd6e6e7b4b48e7fa7d55b431c39ba17e1, but even after backing out all of those changes, the build error persists.

Any help would be appreciated!

wow. the FDA is using Gatsby?! That's so rad.

Apologies for stating the obvious but I think there's an issue with one of your JSON files. This same issue plagued me -- that is, gatsby develop works but gatsby build didn't -- and I got the same error. I narrowed it down by commenting out all the references to JSON files, running gatsby build, then uncommenting each reference until the error popped back up. I was able to narrow it to one file. Scanning the file, I found a missing ,. It happened a week later and the issue was incorrect lat/long values.

I'm super curious of your results. I'm happy to dig further but try a few of those tricks and let us know what you find. Good luck!

It's almost certainly the same issue as https://github.com/gatsbyjs/gatsby/issues/3094

Working on fixing this now 👍

Thanks, @benjaminhoffman. I ended up finding that this seems to be an issue with the latest version of gatsby. I found issue #3094 and reverted gatsby back to 1.9.123 on a hunch. Everything builds fine after this - it looks like there's some sort of issue with long JSONs in the latest versions of gatsby.

I manually scanned and machine validated all of our JSONs to ensure there weren't any errors in them, and found that the error wasn't occurring consistently or related to any specific one of them. This is definitely an odd one to troubleshoot.

In any event, reverting fixed the issue for now. I'll follow #3094 for updates. Sorry for the duplicate issue!

@beardedfinch try the latest gatsby release when you have a chance. #3218 should have fixed the problem you were running into. Would love to hear back if it's working now for ya.
