Not sure why the Travis build is failing. Working okay locally for me.

@mateusmarquezini - can you try pulling this branch and doing an npm i and then npm t and see if it builds clean for you locally?

[mateusmarquezini]

@guyellis sure, I'm going to see what's happening with the build.

@mateusmarquezini is it building and testing clean for you locally? I see this error on Travis but can't reproduce this locally. Can you see anything in the Travis file that would cause this?

@guyellis I can't reproduce it too. Locally everything works fine for me. I think this error should be something about CI config. I'll study that as soon as possible.

@mateusmarquezini - I just locked all dependencies down to an exact version and fixed the merge conflict to see if that would change things...

@guyellis I think the problem is related to jest settings in jest.config.js.

I was following this thread yesterday jestjs/jest#7094 (comment) but it still not working.

@mateusmarquezini - you were on the right path - awesome work! We just needed to relax the exclusion on that path. You solved it!
