[2529] Error loading files after update to 1.0.0

I've updated to nuxt 1.0.0 without changing my code and I have this error

ERROR in ./node_modules/ts-loader?{"appendTsSuffixTo":[{}]}!./node_modules/nuxt/node_modules/vue-loader/lib/selector.js?type=script&index=0!./pages/_lang/serviceworker.vue
Module not found: Error: Can't resolve '~/store/modules/serviceworker' in 'C:\Projects\Microsoft\PWABuilderVue\pages\_lang'
 @ ./node_modules/ts-loader?{"appendTsSuffixTo":[{}]}!./node_modules/nuxt/node_modules/vue-loader/lib/selector.js?type=script&index=0!./pages/_lang/serviceworker.vue 61:0-63
 @ ./pages/_lang/serviceworker.vue

Any idea that why is it happening? That was working before: The import is like:

import * as serviceworker from '~/store/modules/serviceworker';
