Mix 5.0.5: Causing UnhandledPromiseRejectionWarning error

• Laravel Mix Version: 5.0.5 (npm list --depth=0)
• Node Version (node -v): v12.12.0
• NPM Version (npm -v): 6.11.3
• OS: MacOS

Description:

Running npm run dev no longer works once Laravel mix is upgraded to 5.0.5. It’s throwing an UnhandledPromiseRejectionWarning about file/directory not existing, but the files in question exist. This error prevents mix from, well, mixing.

The issue is that these files exist. And if I roll back to Mix 5.0.4, everything works swimmingly.

Full error output:

(node:26595) UnhandledPromiseRejectionWarning: Error: ENOENT: no such file or directory, open '/usr/local/var/www/exedra/resources/assets/js/*.js'
(node:26595) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). (rejection id: 1)

Steps To Reproduce:

package.json file:

{
    "private": true,
    "scripts": {
        "dev": "npm run development",
        "development": "cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
        "watch": "cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --watch --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
        "watch-poll": "npm run watch -- --watch-poll",
        "hot": "cross-env NODE_ENV=development node_modules/webpack-dev-server/bin/webpack-dev-server.js --inline --hot --config=node_modules/laravel-mix/setup/webpack.config.js",
        "prod": "npm run production",
        "production": "cross-env NODE_ENV=production node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js"
    },
    "devDependencies": {
        "cross-env": "^7.0.2",
        "laravel-mix": "^5.0.5",
        "resolve-url-loader": "^3.1.1",
        "sass": "^1.26.10",
        "sass-loader": "^7.1.0"
    }
}

webpack.mix.js file:

let mix = require('laravel-mix');

mix.disableNotifications();
 
// establish known paths for sanity
let vendorPath     = 'node_modules/',
    assetPath      = 'resources/assets/',
    libPath        = assetPath + 'lib/',
    sassPath       = assetPath + 'sass/',
    sassVarPath    = sassPath + 'variables/',
    cssPath        = assetPath + 'css/',
    jsPath         = assetPath + 'js/',
    cvmPath        = 'modules/CompositeViews/',
    cvmAssetPath   = cvmPath + 'Resources/assets/',
    cvmSassPath    = cvmAssetPath + 'sass/',
    cvmSassVarPath = cvmSassPath + 'variables/',
    bvmPath        = 'modules/BinViews/',
    bvmAssetPath   = bvmPath + 'Resources/assets/',
    bvmSassPath    = bvmAssetPath + 'sass/',
    bvmSassVarPath = bvmSassPath + 'variables/';
 
// compile all SASS styles from modules and primary resources
mix.sass(bvmSassPath + 'module.scss', 'assets/css/compiled-bvm.css').setPublicPath('resources');
mix.sass(cvmSassPath + 'module.scss', 'assets/css/compiled-cvm.css').setPublicPath('resources');
mix.sass(sassPath + 'app.scss', 'assets/css/compiled-sass.css').setPublicPath('resources');

// combine javascript files
mix.scripts([
    assetPath + 'descriptor.js',
    jsPath + '*.js'
], 'public/js/app.js');

// combine app styles into one CSS file
mix.styles([
    cssPath + '*.css',
], 'public/css/app.css');

With Laravel Mix 5.0.5 installed, run the following command: npm run dev

Downgrade to Laravel Mix 5.0.4 and run the same command and no error appears. The mix completes without issue.

Thank you. Fixed.

Instead of using an asterisk for all files under specified folder (*.js, *.css etc), use the full file path.

For example:

mix.scripts([ 'resources/js/utility/add_me_to_scripts.js', 'resources/js/filters/you_dont_wanna_forget_me.js' ], 'public/js/app.js');
