it "displays an error with no content" test fails.. click_button "Save" NoMethodError

Performing the second test in the create_spec.rb file "displays an error with no content.... I get an error at click_button "Save" NoMethodError. even though the save type of test was performed earlier successfully. I don't even remember creating a save button. guess I'm lost. Any suggestions on fixing the bug so I can continue? Seems it broke when i added the validation in the todo_item.rb model

class TodoItem < ActiveRecord::Base
  belongs_to :todo_list

  validates :content, presence: true
end

it "is successful with valid content" do
    visit_todo_list(todo_list)
    click_link "New Todo Item"
    fill_in "Content", with: "Milk"
    click_button "Save"
    expect(page).to have_content("Added todo list item.")
    within("ul.todo_items") do
      expect(page).to have_content("Milk")
    end
  end

  it "displays an error with no content" do
    visit_todo_list(todo_list)
    click_link "New Todo Item"
    fill_in "Content", with: ""
    click_button "Save"
    within("div.flash") do
      expect(page).to have_content("There was a problem adding that todo list item.")
    end
    expect(page).to have_content("Content can't be blank.")
  end

Right after test failure "expect(page).to have_content("There was a problem adding that todo list item.")

I've check 100 times and can't find any consistency .. especially whereas the previous test passes with similar requirements.

Check your controller mostly the create method and the error should actually give you the filename and line number
