Build fails with 'filePath' of 'bundle.getMainEntry(...)' as it is undefined.

Hi.

When I hit the command serve or build parcel ./src/index.pug, an error occurs.

Error messages below:

🚨 Build failed.
parcel-namer-custom: Cannot destructure property 'filePath' of 'bundle.getMainEntry(...)' as it is undefined.

parcel version -> 2.0.0-beta.3.1
parcel-namer-custom version -> 0.2.0

Here is .parcelrc

{
    "extends": "@parcel/config-default",
    "namers": ["parcel-namer-custom", "..."],
}

Here is partial of package.json related this plugin

    "parcel-namer-custom": {
        "src/index.pug$": "[name].[type]",
        ".(pug|html)$": "[dir]/[name].[type]",
        ".(js|ts)$": "[dir]/[name].[type]",
        ".styl$": "[dir]/[name].[type]",
        ".(jpg|gif|png|webp|svg)$": "[dir]/[name].[type]",
        ".jsx?$": "scripts/[name].[hash].[type]"
    },

Update:

I load css files in app.js like below.

// head of app.js
import "normalize.css/normalize.css"
import '../css/style.styl' // this is my custom css file.
import 'swiper/swiper-bundle.css'
import Swiper from 'swiper/bundle'

and I let them to be commented out.

// import "normalize.css/normalize.css"
// import '../css/style.styl' // this is my custom css file.
// import 'swiper/swiper-bundle.css'
import Swiper from 'swiper/bundle'

BOOM! Terminal said

parcel-namer-custom: src/index.pug → dist/index.html
/Users/kohkishikata/git-repo/the_repository/src/index.pug
parcel-namer-custom: src/assets/img/logowa.png → assets/img/logowa.png
/Users/kohkishikata/git-repo/the_repository/src/assets/img/logo_wa.png
parcel-namer-custom: src/assets/js/app.js → assets/js/app.js
/Users/kohkishikata/git-repo/the_repository/src/assets/js/app.js

Almost workaround what I expected.

However, I still need to use css in app.js and use npm modules.

Does anyone have any solution?

I am hitting this too, but mine seems to be with including another local JS file.
