"" (empty string) is the JSON pointer pointing to the root of a document.

This code fails with error invalid character 'u' looking for beginning of value. Check on the Go Playground.

package main

import (
	"testing"

	"github.com/lestrrat-go/jsonptr"
)

func TestGet(t *testing.T) {
	doc, err := jsonptr.Parse([]byte(`null`))
	if err != nil {
		t.Error("valid doc")
	}
	var v any
	err = doc.Unmarshal("", &v)
	if err != nil {
		t.Errorf("valid pointer but got error: %q", err)
	}
	if v != nil {
		t.Error("null expected")
	}
}
