Hello,

First of all, loving Sage, awesome stuff

But recently I have encountered a problem which left me completely stuck, screenshot: https://nimb.ws/eV84HR

Here’s a publicly accessible link: https://exfactory.invsbl.lt/

This error has come up in few projects (both sage10 + BR) in my local environment (Valet on MacOS) after adding a package via Composer. The public link is a Plesk server, so the problem doesn’t seem to be my local environment.

First project crashed after https://github.com/generoi/sage-woocommerce
Second https://wordpress.org/plugins/spatie-ray/

Although I’m pretty sure packages themselves are not to blame. Also, both projects were just started and had almost none custom functionality. Interestingly, in neither cases, it was a first installed package, everything was working fine for a while and after adding a 4th plugin, things just stopped working.

If I comment out script enqueueing function, the error disappears:

add_action('wp_enqueue_scripts', function () {
    wp_enqueue_script('sage/vendor.js', asset('scripts/vendor.js')->uri(), ['jquery'], null, true);
    wp_enqueue_script('sage/app.js', asset('scripts/app.js')->uri(), ['sage/vendor.js'], null, true);
wp_add_inline_script('sage/vendor.js', asset('scripts/manifest.js')->contents(), 'before');

    if (is_single() && comments_open() && get_option('thread_comments')) {
        wp_enqueue_script('comment-reply');
    }

    wp_enqueue_style('sage/app.css', asset('styles/app.css')->uri(), false, null);
}, 100);

I would appreciate any help, thanks a lot.

Also, here’s composer.json if that’s any help

What’s on line 17 of your setup.php?

[karolisVSBL]

It’s the first wp_enqueue_script function in this action:

add_action('wp_enqueue_scripts', function () {
wp_enqueue_script('sage/vendor.js', asset('scripts/vendor.js')->uri(), ['jquery'], null, true);
wp_enqueue_script('sage/app.js', asset('scripts/app.js')->uri(), ['sage/vendor.js'], null, true);

wp_add_inline_script(‘sage/vendor.js’, asset(‘scripts/manifest.js’)->contents(), ‘before’);

if (is_single() && comments_open() && get_option('thread_comments')) {
    wp_enqueue_script('comment-reply');
}

wp_enqueue_style('sage/app.css', asset('styles/app.css')->uri(), false, null);

}, 100);

It’s something with asset() function, I’ve temporary replaced it and everything’s working well:

    // wp_enqueue_script('sage/vendor.js', asset('scripts/vendor.js')->uri(), ['jquery'], null, true);
wp_enqueue_script('sage/vendor.js', get_template_directory_uri() . "/public/scripts/vendor.js", ['jquery'], null, true);

// wp_enqueue_script('sage/app.js', asset('scripts/app.js')->uri(), ['sage/vendor.js'], null, true);
wp_enqueue_script('sage/app.js', get_template_directory_uri() . "/public/scripts/app.js", ['sage/vendor.js'], null, true);
