{{define "Index"}}
<!DOCTYPE html>
<html lang="en">

    <title>Alura loja</title>
</head>
<nav class="navbar navbar-light bg-light mb-4">
    <a class="navbar-brand" href="/">Alura Loja</a>

<body>
    <div class="container">
        <section class="card">
            <div>
                <table class="table table-striped table-hover mb-0">
                    <thead>
                        <tr>
                            <th>Nome</th>
                            <th>Descrição</th>

                    </thead>
                    <tbody>
                        {{range .}}
                        <tr>
                            <td>{{.Nome}}</td>
                            <td>{{.Descricao}}</td>
                            <td>{{.Preco}}</td>
                            <td>{{.Quantidade}}</td>
                            <td><a href="/delete?id={{.id}}" class="btn btn-danger">Deletar</a></td>
                        </tr>
                        {{end}}
                    </tbody>
                </table>
            </div>
        </section>
        <div class="card-footer">
            <a href="/new" class="btn btn-primary mb-2">Novo Produto</a>
        </div>
    </div>
</body>

</html>
{{end}}

Na linha da td quando passo o href com o parametro "/delete?id={{.id}}" esta linha para de rederizar e quebra toda minha lista. O que poderia seria?
