Return value of Spatie\Valuestore\Valuestore::all() must be of the type array, null returned

Hi, we just started using this on a site and during development we have had no problems with it, but we set it up on production, and set an error tracker, and it seems like every now and then we get a weird error from this.

It feels on a put line in the settings provider:

class SettingsServiceProvider extends ServiceProvider {


    /**
     * Bootstrap services.
     *
     * @return void
     */
    public function boot() {
        if (today() > Carbon::create(date('Y'), 12, 14)) {
            $year = date('Y') + 1;
        } else {
            $year = date('Y');
        }
        $this->app->settings->put('registration_year', $year);
    }

    /**
     * Register services.
     *
     * @return void
     */
    public function register() {
        $this->app->singleton('settings', function ($app) {
            return Valuestore::make(database_path('settings.json'));
        });
    }
}

The line it always fails on is: $this->app->settings->put('registration_year', $year); and the error is always

Return value of Spatie\Valuestore\Valuestore::all() must be of the type array, null returned

So far we haven't managed to recreate it, but it bothers me....

any chance you know what could be causing it? thanks!

Dear contributor,

because this issue seems to be inactive for quite some time now, I've automatically closed it. If you feel this issue deserves some attention from my human colleagues feel free to reopen it.

It might be a little late and I hope you have already solved the problem, and for others having the same issue,
initialize the settings.json ( where you're going to store the key value pairs) file with json object brackets.
{ }

Could you be more specific about how to solve this?
Because I also get this error and I can't find where and when it happens and how to fix it.

I'm running into this issue as well, and it's really difficult to debug as it seemingly randomly throws this error. @jason-guru I think your solution is for when you settings.json file is empty, right? My settings.json file already has values, so this won't solve the issue.

I initially thought that this error was caused by 2 processes that simultaneously tried to update the settings.json file. So I changed this so that each process has a different settings file, yet the error still occurs.

@nuz did you eventually solve it?

Finally I removed the package and put my values from database to config file.

Can you please help me to fix the above error.

I fixed it by encoding the data in my array to utf-8. (cfr example function from Stack Overflow)

function utf8ize($d) {
 if (is_array($d)) {
        foreach ($d as $k => $v) {
            $d[$k] = utf8ize($v);
        }
    } else if (is_string ($d)) {
        return utf8_encode($d);
    }
    return $d;
}
