I'm having the same problem. It's fine with Laravel 5.3 but getting the "array_key_exists() expects parameter 2 to be array, boolean given" error in Laravel 5.4.

you could add some small workaround. I changed one line in file "vendor/proengsoft/laravel-jsvalidation/src/JsValidatorFactory.php" on line 157 from:
$formRequest = $this->app->build($class, $params);
to:
$formRequest = new $class;
it seems to work on all my projects that use Laravel 5.4.19 but that's probably not the best solution, but it works :)
of course for Laravel 5.4 I also using this patch: Add Support For Laravel 5.4

You can use my temporary repository.

1. In composer.json change proengsoft/laravel-jsvalidation in require section to this one:

"proengsoft/laravel-jsvalidation": "dev-dev-laravel54",

2. Add repositories section with following content:

    "repositories": [
        {
            "type": "git",
            "url": "https://github.com/cybercog/laravel-jsvalidation"
        }
    ],

3. Execute composer update.

When fix will be published in official repository just revert proengsoft/laravel-jsvalidation to previous value and remove custom repository from repositories section.

Laravel Container was fixed in recent PR. It will be included in next Laravel release.
