Insufficient funds error with sendTransaction using account signing

[guifel]

Description

Using beta 48. I try to send a transaction from an address with sufficient balance with the private key stored in the account module.

Expected behavior

Transaction should go through (Or display a different error message if I am missing something).

Actual behavior

Balance:  39558999999999700
(node:5972) UnhandledPromiseRejectionWarning: Error: Node error: {"code":-32000,"message":"insufficient funds for gas * price + value"}

    at process._tickCallback (internal/process/next_tick.js:188:7)

Steps to reproduce the behavior

const web3 = new Web3(new Web3.providers.HttpProvider('https://rinkeby.infura.io/v3/<API_KEY>'));
const alicePrivateKey ='<PRIV_KEY>'
web3.eth.accounts.wallet.add(alicePrivateKey)
const alice = web3.eth.accounts.privateKeyToAccount(alicePrivateKey).address
web3.eth.getBalance(alice).then(x => console.log("Balance: ", x.toString()))
const bob = '0x829bd824b016326a401d083b33d092293333a830'
web3.eth.sendTransaction({from: alice, to: bob, value: "100", gas: 30000, gasPrice:'1000000000'}).then(x => console.log(x))

The same code works for beta 36. On beta 46 I get the error TypeError: Cannot create property 'from' on string '0xf86303843b9aca0082753094829bd824b016326a401d083b33d092293333a83064802ca039e64f244297c5791cc004dfdb82036f270594d0e60254f8095d24a987a481e5a072f761082059a356c9be2997bf90a6ef6afab3e61b7758385aec80d4e9af21f9' at Object.inputTransactionFormatter

Tried on nodejs and Chrome.

Versions

• web3.js: beta 48
• nodejs: v8.10.0
• ethereum node: infura and local parity node

The returned value from getBalance is in wei this means the balance of this account is ~0.03955 ether. Which isn't enough for executing this transaction.

[guifel]

The balance is enough:
(1000000000*30000+100)*10**-18 = 0.00003 < 0.03955

As I said, the same works on beta 36

Since I don't have access to the specifics of your env, could you test the same code but with gas price set to 0? That could help us narrow it down, @guifel.

[guifel]

With gasPrice set to 0

If I don't specify any gas price I get the same error as on my issue description.

There is already an existing issue about this and I think we should discuss it here.

@guifel Yep, this is correct I was wrong because I thought the value property is in ether. In the issue, I've referenced above are some additional information about this.

For the logs: One reason why this could happen is missing hex-encoding of the gas values:

let rawTx = {
  nonce: web3.toHex(nonce),
  to: null,
  data: bytedata,
  gasPrice: web3.toWei('2', 'gwei'),
  gas: (318019 * 2),
  value: '0x00'
}

you would think this means we will pay 318019 * 2 = 636038 gas, by a price of 2gwei, should be = 1272076 gwei = 0.001272076 ether.
But with 0.20.x i get this error on Kovan-testnet:

The account you tried to send transaction from does not have enough funds. Required 150745611034260441820719413536 and got: 992632048000000000

which is ~150745611034 ether ^^
fix:

let rawTx = {
[...]
  gasPrice: web3.toHex(web3.toWei('2', 'gwei')),
  gas: web3.toHex((318019 * 2)),
}
