Laravel-8不允许序列化“关闭”

Question

我正在博客站点上工作，因此我尝试使用Summer note文本编辑器插入文本。我面临的问题是，在提交了详细的文本后，Laravel抛出了一个错误，那就是-

我的控制器代码

$data = [
                'user_id' => Auth::id(),
                'blog_title' => $request->title,
                'blog_slug' => $slug,
                'category_id' => $category,
                'blog_summery' => $request->summary,
                'blog_details' => $request->summernote,
                'thumbnail' => $file
            ];

            try {
                Blog::create($data);
                //store image into storage directory
                Storage::putFileAs('public/blogs', $image, $file);

                $notification = [
                    'message'   =>  'nothing went wrong',
                    'alert-type'    =>  'success'
                ];
        
                return redirect()->back()->with($notification);

            } catch (\Throwable $th) {
                $notification = [
                    // 'message'   =>  'oops! Something went wrong',
                    'message'   =>  $th->getMessage(),
                    'alert-type'    =>  'warning'
                ];
        
                return redirect()->back()->with($notification);
            }

博客表迁移

public function up()
    {
        Schema::create('blogs', function (Blueprint $table) {
            $table->id();
            $table->integer('user_id');
            $table->string('blog_title', 100);
            $table->string('blog_slug', 100);

            $table->unsignedBigInteger('category_id')->nullable();
            $table->foreign('category_id')
            ->references('id')
            ->on('categories')
            ->onDelete('set null')
            ->onUpdate('cascade');

            $table->string('blog_summery');
            $table->text('blog_details');
            $table->string('thumbnail', 100);
            $table->timestamps();
        });
    }
