No implicit conversion Error while extracting nested parameter in Rails self method

Question

I am trying to implement search functionality based on parameters by passing into rails model self method. While checking passed parameter conditionally on query I am getting no implicit conversion of Symbol into Integer.

my article.rb file like the following

 class Article < ApplicationRecord

  has_many :article_categories
  has_many :categories, through: :article_categories
  validates :title, presence: true, length: { minimum: 6, maximum: 100 }
  validates :description, presence: true, length: { minimum: 10, maximum: 300 }

  def self.search_artcat(params)
     @articles = Article.where(title: params[:article][:title]) if params[:article][:title].present?
  end 

end

I am accessing title and description from article parameter.

Can anyone guide me to resolve this error in my query ?
