LayerZero: Wrong path data #37
Description
I am trying to send an OFNTv2 from fuji to goerli I am running into LayerZero: wrong path data error but cannot see where the contract calls the send function.
Below is my code:
const { ethers } = require("hardhat")
require('dotenv').config()
// Initiate token names
const NAME = "TestBridge"
const SYMBOL = "TESTBRIDGE"
const SHARED_DECIMALS = 5
const firstEndpoint = '0x93f54D755A063cE7bB9e6Ac47Eccc8e33411d706'
const secondEndpoint = '0xbfD2135BFfbb0B5378b56643c2Df8a87552Bfa23'
const firstLZId = 10106
const secondLZId = 10121
// Initiate two ethers instances 1 for each chain
const firstProvider = new ethers.JsonRpcProvider(process.env.FUJI_RPC_URL)
const secondProvider = new ethers.JsonRpcProvider(process.env.GOERLI_RPC_URL)
const firstWallet = new ethers.Wallet(process.env.PRIVATE_KEY, firstProvider)
const secondWallet = new ethers.Wallet(process.env.PRIVATE_KEY, secondProvider)
const initialAmount = ethers.parseEther("1.00000001").toString() // 1 ether
const amount = ethers.parseEther("1.00000000")
const dust = ethers.parseEther("0.00000001")
const abiCoder = ethers.AbiCoder.defaultAbiCoder()
const walletAddressBytes32 = abiCoder.encode(["address"], [firstWallet.address])
