"Array to string conversion" error when opening (empty) Collection

[MrMooky]

Bug description

When opening a collection overview, I suddenly get the following error:

Array to string conversion (View: /x/y/vendor/statamic/cms/resources/views/collections/empty.blade.php).

I had the same error when there were entries in the collection, but only with show.blade.php instead of empty.blade.php.

Cleared all caches, dumped autoload... error is still there.

How to reproduce

Not really sure. The collection is empty now and there is nothing I can think of. This is the config for the collection:

title: News
sites:
  - default
  - en
propagate: false
template: cms/news/show
layout: layout
revisions: false
route: 'news/{slug}'
date: true
sort_dir: asc
date_behavior:
  past: public
  future: private

This has something to do with that livewire package. Could you open an issue there instead?

[MrMooky]

This has something to do with that livewire package.

What makes you think that?

[jasonvarga]

The stack trace you provided shows the livewire component as the cause.

Click the "+ 77 vendor frames..." and you'll see the second frame is coming from livewire.

I just removed both addons, cleared all caches and the error remains.

Statamic 3.3.19 Pro
Laravel 9.19.0
PHP 8.1.4
No addons installed

The stacktrace is identical. I'm not using Livewire anywhere in the backend myself and the error appears when opening the route Statamic\Http\Controllers\CP\Collections\CollectionsController@show.

Now here is the fun part: I also completely removed Livewire from composer, cleared caches, dumped composer autoload and that error is still pointing to Livewire. o_O I also debugged the source in the vendor folder.

The line @section('title', Statamic::crumb($collection->title(), 'Collections')) is causing the error, but only in the News collection. Other collections work just fine, for whatever reason.

The function crumb expects an array (?) it seems, but is getting a string, either "News", or "Projects" in my case.

public static function crumb(...$values)
{
    return implode(' ‹ ', array_map('__', $values));
}

Not sure though why Livewire is still in the stacktrace.

I just tried to rebuild this outside of Statamic within a simple test function and get the same error (no Livewire or anything):

[jasonvarga]

In your crumbX method, can you dump($values)?

    private function crumbX(...$values)
    {
        dump($values);
        return implode(' ‹ ', array_map('__', $values));
    }

Do you have a news.php translation file?

[MrMooky]

Do you have a news.php translation file?

Yes, I do. And after renaming it, the error is gone. 🙈 Really odd. Is that the "fix"? I'm having a déjà vu right now. I think you and I discussed this already in another issue a while back.

[jasonvarga]

It's okay I have a fix. It'll be in the next release.
