Error 404 when using simple find methods

On android, I try to find my items
I am on rspec in ruby.

When I do
find_element(:name, "Explore").click
everything is right, but if I try
find('Explore').click
I get this:

Failure/Error: @driver.find(‘Explore’).click
Selenium::WebDriver::Error::WebDriverError:
unexpected response, code=404, content-type=“text/plain”
That URL did not map to a valid JSONWP resource

Same if I try to use other methods like scroll_to('Entertainment').click

solved…
due to a copy of the gemfile on samples, which linked on appium lib v3 instead of 6…
