WARN: Screenshot could not be saved. page.current_path is empty

Question

I'm running the test using bundle exec rspec, which gives me the error of:

WARN: Screenshot could not be saved. page.current_path is empty.

also getting this error:

1) adding a new task can re-order a task
     Failure/Error: expect(page).to have_selector(".name", text: "Take Notes")
       expected to find visible css ".name" with text "Take Notes" within #
<Capybara::Node::Element tag="tr" path="/HTML/BODY[1]/TABLE[1]/TBODY[1]/TR[2]"> but there were
 no matches. Also found "Use Telescope", which matched the selector but not all filters. 

Ruby: 2.7.2 Rails: 6.0.3.4

After the following test, I got the error.

Here's the test I'm trying to test: /spec/system/add_task_spec.rb

require "rails_helper"

RSpec.describe "adding a new task" do
  let!(:project) { create(:project, name: "Project Bluebook") }
  let!(:task_1) { create(
    :task, project: project, title: "Search Sky", size: 1, project_order: 1) }
  let!(:task_2) { create(
    :task, project: project, title: "Use Telescope", size: 1,
           project_order: 2) }
  let!(:task_3) { create(
    :task, project: project, title: "Take Notes", size: 1,
           project_order: 3) }

  it "can re-order a task", :js do
    visit(project_path(project))
    find("#task_3")
    within("#task_3") do
      click_on("Up")
    end
    expect(page).to have_selector(
      "tbody:nth-child(2) .name", text: "Take Notes")
      #END:P1
      #START:P2
    visit(project_path(project))
    find("#task_2")
    within("#task_2") do
      expect(page).to have_selector(".name", text: "Take Notes")
    end
  end

end

Answer 1

I resolved the error by changing the test like this:

  it "can re-order a task" do
    visit(project_path(project))
    find("#task_3")
    within("#task_3") do
      click_on("Up")
    end
    
    expect(page).to have_selector("tbody:nth-child(2) .name", text: "Take Notes")
    visit(project_path(project))
    within("#task_2") do
      expect(page).to have_selector(".name", text: "Use Telescope")
    end
  end
