Describe the bug

89 |  * // '0x48656c6c6f20576f726c64210000000000000000000000000000000000000000'

90 |  */

91 | export function bytesToHex(value, opts = {}) {

92 |     let string = '';

93 |     for (let i = 0; i < value.length; i++) {

                             ^

TypeError: undefined is not an object (evaluating 'value.length')

Cast composer actions do not have a cast and so this line fails

@dalechyn would appreciate a quick patch and release on this one. Thanks!

that's a neat catch, thanks! I wonder why is buttonIndex passed for backwards compatibility but cast_id not, but that's a question for another day.
