content is probably :enoent, which again is a “POSIX” error, which tells you that some “entity did not exist”.

You probably read the content from a file that did not exist.

This is the code that is giving the content aka errors.

    with {:ok, :done} <- download_csv(csv_path) do
      read_csv("files/" <> csv_path) 
        |> dump_to_csv
        |> add_attachment
        |> Email.create(email)
        |> Email.send_email
      File.rm("files/" <> csv_path)
    else
      {:error, errors} -> Email.create_error_mail(email, errors) |> Email.send_email
    end
  end

How can I fix that, please let me know?

download_csv is downloading csv from the S3 bucket.

My assumption is, that download_csv/1 returns {:error, :enoent}, as only from there it can fall into the with/1s :else branch.

Yes, you are correct.

Thanks.
