I get this error that shows up whenever I use http::persistent. If i simply let capybara run the default http client or if i set the default http client, there is no error.

I'm not configuring persistent at all Selenium::WebDriver::Remote::Http::Persistent.new

gems i'm using

gem 'selenium-webdriver', '3.14.0'
gem 'net-http-persistent', '~> 3.0.1'
gem 'capybara', '3.7.1'
gem 'cucumber', '3.1.2'

undefined method `map' for true:TrueClass

This appears to be a bug in selenium, I see SeleniumHQ/selenium#4555 referenced here a few lines above the last line of your backtrace.

Digging through more of selenium-webdriver it seems you can pick whether it uses net-http-persistent or not (see this search), but I'm not sure how that is performed.

Please ask the selenium people for support in this, perhaps they have some bug in their use of net-http-persistent?

Still happens from time to time in my tests:
