question about split filter on new line

[shomodj]

I'm trying to split a string on new line

package main

import (
	"fmt"
	"github.com/flosch/pongo2"
)

func main() {
	templateString := `
{% for val in my_string|split:'\n' %}
  {{ val }}
{% endfor %}
	`

	template, err := pongo2.FromString(templateString)
	
	if err != nil {
		fmt.Println("Error:", err)
		return
	}

	context := pongo2.Context{
		"my_string": "Line 1\nLine 2\nLine 3",
	}

	output, err := template.Execute(context)
	if err != nil {
		fmt.Println("Error:", err)
		return
	}

	fmt.Println(output)
}
	`

	template, err := pongo2.FromString(templateString)

But I get this error Error: [Error (where: lexer) in <string> | Line 2 Col 31] Unknown escape sequence: \n

Is this possible?
Thanks
