🚩 Challenge 1: I Can't Send My Transaction! 😭

I want to send 1 ALGO to my friend to show how amazing Algorand is but I can't send my transaction! what's wrong???

algokit bootstrap all
algokit localnet start
npm run start

it will fail and show this error: TypeError: Argument must be byte array

This repository has the challenge folder on the root level, which contains the fix the bug challenge codebase. Find the index.ts file inside of the challenge folder and fix the bug! 🐞
