Deploying contract is always pending . Using web3 to deploy contract

Question

Here is my code for deploying contract

I get transaction hash, but transaction showing pending alway.

I am doing this on Rinkeby network.

var myContract = new web3.eth.Contract(abiDefinition);

var contract =  myContract.deploy({
      data: bytecode,
      //  uint64 maxBalance, uint64 maxSupply, string coinName,uint8 decimalPlace,string simbol, uint unitToSell
      arguments: [deployeParam.max_bal, deployeParam.max_sup, deployeParam.coin_name, 8, deployeParam.symbol, deployeParam.unit_to_sup]
    });


contract.estimateGas().then(function(gas){
  var params = {
    from: web3.eth.coinbase,
    gas: 5000000
  }

  contract.send(params, function (error, transactionHash) {
    if (error) {
      console.log(error);
      $j("#page_loader").hide();
      toastr.error(error);
    }
    console.log(transactionHash);
  })
  .on('error', function (error) {
    $j("#page_loader").hide();
    toastr.error(error);
    console.log(error);
  })
  .on('transactionHash', function (transactionHash) {
    //setData('contracttransactionhash', transactionHash, false);
    $j("#txhash").text(transactionHash);
    setEtherscanIoLink('contracttransactionhash_link', 'tx', transactionHash);
    result.transactionHash = transactionHash;
   // deployecallback(result);
    $j("#page_loader").hide();
  })
  .on('receipt', function (receipt) {
    console.log(receipt.contractAddress) // contains the new contract address
    document.getElementById('contractaddress').value = receipt.contractAddress;
    setEtherscanIoLink('contractaddress_link', 'address', receipt.contractAddress);
  })
  .on('confirmation', function (confirmationNumber, receipt) {
    console.log(confirmationNumber);
    console.log(receipt);
  });
});

Answer 1

The transaction in pending state has nonce set to 12 and if you look at the from account it has no outgoing transaction.

Nonces used in transactions have to be consecutive numbers starting from 0.

For your account the nonce to be mined next should be zero because there's no previous outgoing transaction. Programatically you have to call web3.eth.getTransactionCount to obtain the nonce to use.

Your code does not set the nonce so it should be set by the node you are using. Perhaps do you have other transactions pending?
