Hi was missing the do command, for the suggested parameters, but it still throws the same error about the genesis hash.
I debugged the code, and checked the value of the params variable, and it’s populated with data.
Code below;
const algosdk = require(“algosdk”);
const {validate, printError, algod} = require(“./utils”);
// DO NOT CHANGE
const challenge_id = “3474867148855516251”
const client = new algosdk.Algodv2(algod.token, algod.server, algod.port);
let txids = ;
let params = client.getTransactionParams().do();
const sk = “REMOVED”; // TODO: Paste your secret key here. You can find it underneath the code editor.
// Decode the secretKey into a Uint8Array from base 64
// This will produce an array of length 64
const secret = new Uint8Array(Buffer.from(sk, “base64”));
const acct = {
// The public key is the secret[32:], or the last 32 bytes
// We encode it to the address which is easier to read and includes a checksum
addr: algosdk.encodeAddress(secret.slice(32)),
// We need not do anything with the secret
sk: secret,
};
(async function () {
try {
// Get the suggested parameters from the Algod server. These include current fee levels and suggested first/last rounds.
const sp = algosdk.ALGORAND_MIN_TX_FEE; // TODO: use the client initialized above to get the suggested parameters from the algod server
// Create a payment transaction from you to you using the `acct` variable defined above
const ptxn = algosdk.makePaymentTxnWithSuggestedParamsFromObject({
// TODO: Fill out the transaction parameters to send yourself 1 Algo
from: 'BX4OKERATBF2IIIPVAMUEBPGI5YPJPF7ZYZIDVCME3ZS3ZE464GF35LANM', // The from (sender) should be set to your address
to: 'BX4OKERATBF2IIIPVAMUEBPGI5YPJPF7ZYZIDVCME3ZS3ZE464GF35LANM', // The to (receiver) should be set to your address
amount: 1000000, // The amount should be set to 1 algo (Hint: 1 algo is 1 million micro algos)
suggestedParams: params, // Use the suggested parameters you got from the client above
gh: 'SGO1GKSzyE7IEPItTxCByw9x8FmnrCDexi9/cOUJOiI='
});
// Sign the transaction. This should return a Uint8Array representing the bytes to be sent to the network
const signed = undefined; // TODO: Sign the transaction object using the accounts secret key
// Send the transaction, returns the transaction id for the first transaction in the group
const { txId } = await client.sendRawTransaction(signed).do();
txids.push(txId);
// Wait for the transaction to be confirmed.
const result = await algosdk.waitForConfirmation(client, txId, 2);
// Log out the confirmed round
console.log("Confirmed round: " + result["confirmed-round"]);
} catch (error) {
printError(error);
}
if (await validate(challenge_id, txids)) {
console.log(“Success!”);
} else {
console.error(
“Something went wrong, please review the error and try again”
);
}
})();
