Error trying to execute query in Elixir with Ecto-CodePudding

I have an Elixir app that uses Ecto in order to execute queries in Postgres. I have this Ecto schema:

defmodule Person do

  use Ecto.Schema

  schema "person" do
    field :name, :string
  end

end

I'm trying to make a simple select in Elixir:

query = from Person
result = Repo.all(query)

but after executing that code, I see this:

** (FunctionClauseError) no function clause matching in Ecto.Adapters.Postgres.Connection.expr/3

The following arguments were given to Ecto.Adapters.Postgres.Connection.expr/3:

    # 1
    {{:., [], [{:&, [], [0]}, "name"]}, [], []}

    # 2
    {{[34, "Person", 34], [84 | "0"],
      Person}, []}

    # 3
    #Ecto.Query<from c0 in Person,
     select: c0>
