Error during build: registerVersion is not a function

[HaimBendanan]

Hey!

I added this theme in my project and everything works well when running gatsby develop.
But when running gatsby build, I get the following error:

WebpackError: TypeError: _firebase_app__WEBPACK_IMPORTED_MODULE_0___default.a.registerVersion is not a function

 index.esm.js:23 Module../node_modules/firebase/app/dist/index.esm.js
   node_modules/firebase/app/dist/index.esm.js:23:9

   node_modules/gatsby-theme-firebase/src/pages/login.tsx:1:1

Tried to npm install @firebase/app as suggested here: firebase/firebase-tools#1989 but it didn't helped.

Do you have any idea what is going wrong?
