I am getting this error, when I deploy contract by using web3.

This is my code

await web3.eth.accounts.wallet.add({
      privateKey: privateKey,
      address: address 
    });
    defaultAccount = await address;

    const gasPrice = await web3.eth.getGasPrice();
    console.log(gasPrice)
    const gasEstimate = await itemContract.deploy({ data: bytecode, arguments:[1] }).estimateGas();

      await itemContract.deploy({
        data: bytecode,
        arguments:[1]
      })
      .send({
        from: decryptEtherAccount.address,
        gas: gasPrice,
        gasPrice: gasEstimate,
      }).on('error', (error) => {
          console.log("Error: ", error);
      }).on('transactionHash', (transactionHash) => {
          console.log("TxHash: ", transactionHash);
      }).on('receipt', (receipt) => {
        console.log("Address: ", receipt.contractAddress)
      }).then((newContractInstance) => {
          console.log(newContractInstance);   
      }).catch(function(error) {
          console.log(error);
      });

Are there any problem in my code ?

Answer 1

Look carefully at what you are writing:

gas: gasPrice,
gasPrice: gasEstimate,

It should be:

gas: gasEstimate,
gasPrice: gasPrice,
