ESM branch: Webpack > babel-loader error on develop and build commands

[a-kriya]

Description

A sample project exists in gridsome/lib/__tests__/__fixtures__/project-simple which is used as part of e2e test project-simple.build.e2e.js for verifying the build command. With the migration to ESM, the build command and the test currently fails due to a TypeError in the compilation process.

Steps to reproduce

• git checkout esm
• cd gridsome/lib/__tests__/__fixtures__/project-simple
• npm run build

Expected result

A successful build, generating and outputting a single index.html file to dist directory in project-simple, and a passing project-simple.build.e2e.js test.

Actual result

> [email protected] develop
> gridsome develop
