Hi, Welcome to the Infura community!

Could you provide the code you are using to generate the requests?

const HDWalletProvider = require(“truffle-hdwallet-provider”);
const Web3 = require(“web3”);
const { interface, bytecode } = require("./compile");

const provider = new HDWalletProvider(
“mnemonic”,
“https://rinkeby.infura.io/v3/dce50af7b3a347ada43267d2bb80b5b2”
);
const web3 = new Web3(provider);
console.log(“shruti…”);
//try {
const deploy = async () => {
const accounts = await web3.eth.getAccounts();
// console.log(“attempting to deploy from accounts”, account[0]);
const result = await new web3.eth.Contract(JSON.parse(interface))
.deploy({ data: bytecode, arguments: [“Hi there!”] })
.send({ gas: “1000000”, from: accounts[0] });

console.log(“tandon”);
// console.log(“attempting to deploy from account”, getAccounts[0]);
//const result = await new web3.eth.Contract(JSON.parse(interface))
// .deploy({ data: “0x” + bytecode })
// .send({ from: accounts[0] });

console.log(interface);
console.log(“contract deploed to”, result.options.address);
};

deploy();

I tested your provided API key and it is functioning as expected, this could be an issue with how you are executing Web3.js. Does the deploying account have sufficient Rinkeby ether to deploy the contract?

Hi @Sirine_Hml - welcome to the Infura community! Just to clarify - the account[0] you’re referencing is an ETH address?
