[Ethereum] Call contract methods with web3 from newly created account

I need to call methods from my contract in Ethereum without using MetaMask. I use Infura API and try to call my methods from account, recently created with web3.eth.create() method. This method returns object like this:

{
    address: "0xb8CE9ab6943e0eCED004cG5834Hfn7d",
    privateKey: "0x348ce564d427a3311b6536bbcff9390d69395b06ed6",
    signTransaction: function(tx){...},
    sign: function(data){...},
    encrypt: function(password){...}
} 

I also using infura provider:

 const web3 = new Web3(new Web3.providers.HttpProvider(
    "https://rinkeby.infura.io/5555666777888"
  ))

So, when I try to write smth like that:

contract.methods.contribute().send({
          from: '0xb8CE9ab6943e0eCED004cG5834Hfn7d', // here I paste recently created address
          value: web3.utils.toWei("0.5", "ether")
        });

I have this error:

Error: No "from" address specified in neither the given options, nor
the default options.

How it could be no from address if I write it in from option??

P.S. With Metamask my application works fine. But when I logout from MetaMask and try to create new account with web3.eth.create() method and use it, I have that issue.
