This completely ignores the error.

What you want is to send the error back up, without the need to be super verbose with

        if err != nil {
                return nil, err
        }

He doesn't want to ignore the error, he wants exceptions-like behavior where the exceptions just propagate up by themselves if you don't catch them inside the function. Like Java or Python exceptions.

The goal is not to ignore the error but to make it easier to propagate it. Similar to Haskell’s do form or rust’s ? operator.
