Submit form data to database

I have one general article model that I want to add comments to

Schema::create('article_comments', function (Blueprint $table) {
   $table->BigIncrements('id');
   $table->unsignedBigInteger('article_id');
   $table->foreign('article_id')
      ->references('id')->on('articles')->onDelete('cascade');
   $table->string('name', 128);
   $table->string('email', 128);
   $table->text('text');
   $table->timestamps();

I created a form, substituted values ​​there

<?php

use \App\Models\Article;
    
/**
* @var ArticleBlock $article
*/
?>

<form method="post" action="{{ route('send-comment') }}">
    <div class="row">
        <input type="hidden" name="article_id" value="{{ $article->id }}" />
        <div class="col-md-6">
            <div class="form-item">
                <label for="name">Your Name *</label>
                <div class="input-wrapper">
                    <img src="/img/user.svg" alt="user logo">
                    <input id="name" type="text" name="name">
                </div>
            </div>
        </div>
        <div class="col-md-6">
            <div class="form-item">
                <label for="email">Your Email *</label>
                <div class="input-wrapper">
                    <img src="/img/mail.svg" alt="mail logo">
                    <input id="email" type="email" name="email">
                </div>
            </div>
        </div>
        <div class="col-md-12">
            <div class="form-item">
                <label for="text">Comment *</label>
                <div class="input-wrapper">
                    <img src="/img/comment-alt.svg" alt="comment-alt logo">
                    <textarea id="text" name="text"></textarea>
                </div>
            </div>
        </div>
    </div>
    <input class="submit-button" type="submit" value="Submit Comment">
</form>

Route

Route::post('send-comment', 'App\Http\Controllers\ArticleController@sendComment')->name('send-comment');

Function in the controller

public function sendComment(Request $request)
    {
        $articleComment = new ArticleComment;

        $articleComment->name = $request->get('name');
        $articleComment->email = $request->get('email');
        $articleComment->text = $request->get('text');
        $artile = Article::find($request->get('article_id'));
        $article->article_comments()->save($articleComment);

        return back();
    }

But in the end, after filling out the form, the data does not come and the comment is not created. And when I click on the submit button, I get this
