Hi @WilliamJageR, welcome! To enable the broadest range of people to help you on this forum, it would be helpful if you could describe your problem in english.

However based on your code, you’re trying to match a list against a map. You should try:

%{"Modelos" => modelos} = model
models |> IO.inspect
