json rpc 2.0 in laravel api errors on add request

I add https://github.com/sajya/server

for making json rpc over my laravel 8.

I just follow the instructions provided here to test it https://sajya.github.io/docs/

All works for the basic example, But if I add params to the curl string an error is raised an error that i cannot understand:

my code:

<?php

declare(strict_types=1);

namespace App\Http\Procedures;
use Sajya\Server\Procedure;

use Illuminate\Http\Request;

class PharmaciesProcedure extends Procedure
{
    /**
     * The name of the procedure that will be
     * displayed and taken into account in the search
     *
     * @var string
     */
    public static string $name = 'pharmacies';


    public function ping(Request $request)
    {
        return $request->input('innings');
    }
}

my route api file:

<?php

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Route;
use App\Http\Procedures\PharmaciesProcedure;


Route::rpc('/test1', [PharmaciesProcedure::class])->name('rpc.endpoint');

this request works:

curl 'http://127.0.0.1:8000/api/test1' --data-binary '{"jsonrpc":"2.0","method":"pharmacies@ping","params":[],"id" : 1}'

This not:

curl 'http://127.0.0.1:8000/api/test1' --data-binary '{"jsonrpc":"2.0","method":"pharmacies@ping","params":["innings": "out"],"id" : 1}'

the error:
