undefined method `message' for "TypeError: window.textContent is undefined":String (NoMethodError)

Ruby map error

class DriverJSError < StandardError; end

AfterStep do |scenario, step|
  errors = page.driver.browser.manage.logs.get(:browser)
    .select {|e| e.level == "SEVERE" }
    .map(&:message)
    .to_a

  if errors.any?
    message = errors.map(&:message).join("\n\n")
    raise DriverJSError, message
  end
end


// Sometimes it throws the following error
// undefined method `message' for "TypeError: window.textContent is undefined":String (NoMethodError)

This works for now:

class DriverJSError < StandardError; end

# Some errors are thrown by Selenium but are not
# actual application errors. Those we completely
# ignore
false_positive_errors = [
  "TypeError: window.textContent is undefined"
]

AfterStep do |scenario, step|
  errors = page.driver.browser.manage.logs.get(:browser)
    .select {|e| e.level == "SEVERE" }
    .map(&:message)
    .to_a

  if errors.any?
    uniq = errors.uniq  # removes duplicate errors
    message = uniq.join("\n\n") 

    if false_positive_errors.include?(message)
    else
      raise DriverJSError, "(Cucumber encounter JavaScript errors in the App) " + message
    end

  end
end
