It seems I have a bit of trouble deploying a contract to testnet through infura
this is my code:
var Web3 = require('web3');
var web3 = new Web3(new Web3.providers.HttpProvider('https://rinkeby.infura.io/ETw0GZkwyCWpiOLpvHAw'));
var account = web3.eth.accounts.privateKeyToAccount('5e8bdde40096190506b3182c29aaf068ef5ff3b0dc989ee7e0874ca6873b9fe5');
var _randomSeed = 12; var myContractInstance = new web3.eth.Contract([...]);
myContractInstance.deploy({
data: '0x...',
arguments:[_randomSeed] }).send({
from: account.address//,
// gas: 1500000,
// gasPrice: '30000000000000'
}, function(error, transactionHash){ console.log(error, transactionHash); })
.on('error', function(error){ console.log(error); })
.on('transactionHash', function(transactionHash){ console.log(transactionHash); })
.on('receipt', function(receipt){
console.log(receipt.contractAddress) // contains the new contract address
})
.on('confirmation', function(confirmationNumber, receipt){ console.log(confirmationNumber, receipt); })
.then(function(newContractInstance){
console.log(newContractInstance.options.address) // instance with the new contract address
});
I am able to get the balance of an address so it connects to the node but I get this error when I do .send() after .deploy()

Do you have any idea why this happens or how can I solve it?
