I want to increase the number of target data by one by sending POST in request spec, but I get Can't verify CSRF token authenticity.

 expected Project:: ActiveRecord_Associations_CollectionProxy #count to have changed by 1, but was changed by 0

require 'rails_helper'

RSpec.describe "ProjectsApis", type: :request do
# This test is successful.
    it "create one project" do
      user=FactoryBot.create(:user)
      FactoryBot.create(:project, name: "Sample Project")
      FactoryBot.create(:project, name: "Second Sample Project", owner:user)

      get api_projects_path, params: {
        user_email: user.email,
        user_token —user.authentication_token
      }

      expect(response).to have_http_status(:success)
      json=JSON.parse(response.body)
      expect(json.length).to eq1
      project_id=json[0]["id"]

      get api_projects_path(project_id), params: {
        user_email: user.email,
        user_token —user.authentication_token
