I'm trying to send USDC from one account to another. The code I've attached below worked when we tried sending a dummy erc-20 token. Now, when I try sending USDC from my account to another, I get the following error: Error(code: -32603, message: "Internal error: User denied account access.")
// Send transaction (ERC-20 token)
func sendTransaction(magic: Magic, userPublicAddress: String, amount: Double){
do{
// 3nd instance of web3
let web3 = Web3(provider: magic.rpcProvider)
// Create usdc contract instance
let contractAddress = try EthereumAddress(hex: "0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174", eip55: false)
let contract = web3.eth.Contract(type: GenericERC20Contract.self, address: contractAddress)
