## Code and Dependencies

```go
func defaultBaseTransport(clientCertSource cert.Provider, dialTLSContext func(context.Context, string, string) (net.Conn, error)) http.RoundTripper {
    **trans := http.DefaultTransport.(*http.Transport).Clone()** //this line panics

        trans.DialTLSContext = dialTLSContext
    }

    // Configures the ReadIdleTimeout HTTP/2 option for the
    // transport. This allows broken idle connections to be pruned more quickly,
    // preventing the client from attempting to re-use connections that will no
    // longer work.
    http2Trans, err := http2.ConfigureTransports(trans)
    if err == nil {
        http2Trans.ReadIdleTimeout = time.Second * 31
    }

    return trans
}

Expected behavior

Don't panic

Actual behavior

Panic

panic: interface conversion: http.RoundTripper is *loghttp.Transport, not *http.Transport

The following code is the one that enables new library. opts = append(opts, internaloption.EnableNewAuthLibrary())

// NewService creates a new Service.
func NewService(ctx context.Context, opts ...option.ClientOption) (*Service, error) {
    scopesOption := internaloption.WithDefaultScopes(

    )
    // NOTE: prepend, so we don't override user-specified scopes.
    opts = append([]option.ClientOption{scopesOption}, opts...)
    opts = append(opts, internaloption.WithDefaultEndpoint(basePath))
    opts = append(opts, internaloption.WithDefaultEndpointTemplate(basePathTemplate))
