create new blog-tag occurs an error with the message "insert Blog Tag"

Hi;
When I create a new blog-tag an error occurs with the message "insert Blog Tag"
I solve it by remove "required" from function rules() which inside CreateBlogTagsRequest file (app/Http/Requests/Backend/BlogTags/CreateBlogTagsRequest.php)

public function rules() { return [ 'name' => 'max:191|unique:blog_tags,name,', ]; }
