    optimization: {

        splitChunks: {

            cacheGroups: {

                vendor: {

                    name    : 'vendor',
                    chunks  : 'all',
                    enforce : true,
                    test    : module => { console.log( module.resource ); return false }

                }
            }
        }
    }
}

This is not a bug. Not all modules have a resource property and they are not required to have one.
