Success! Sample data has been added.

Based on this other thread you’re following a books contents. For that case I’d suggest going with the versions you commonly find documented in the start of such books for everything if you can. That includes using an old version of elixir, which would not have those warnings.

If you want to stick to a modern version of elixir you can either also use a modern ecto or ignore the warnings.
