You need to update the version of gatsby in your package.json. You're receiving a really old pre 2.0 release version because of your semver. Changing it to ^2.0.0 fixes the issue.

Hi, sorry for the delay.

I'm currently looking to apply the potential fix.

Hi again,

I put only ^2.0.0 for Gatsby and did a npm install and the issue seems to have been fixed.

Thanks a lot! :) 👍
