Thank you for opening this!

You should remove the .babelrc file as it changes the behavior how Gatsby compiles it code: https://github.com/knnyczr/vantrannguyen/blob/master/.babelrc

Please open an issue at https://github.com/contentful-userland/gatsby-contentful-starter to see why it was added in the first place.

We're marking this issue as answered and closing it for now but please feel free to comment here if you would like to continue this discussion. We also recommend heading over to our communities if you have questions that are not bug reports or feature requests. We hope we managed to help and thank you for using Gatsby!
