Estoy tratando de usar el siguiente código para enviar ripple (Cryptocurrency Coin) - XRP a otra dirección, pero recibo el siguiente error:

"Error no detectado (en promesa): la URL del grifo no está definida o no se puede inferir".

Incluida la siguiente referencia JS en el archivo HTML,

script src="https://unpkg.com/xrpl@2.0.0/build/xrpl-latest-min.js" script type="aplicación/javascript" src="enviar-xrp.js"

¿¿¿Qué me estoy perdiendo???
