I have an error after I send signedTransaction always return error node:

(node:16924) UnhandledPromiseRejectionWarning: Error: Transaction has been reverted by the EVM: { "blockHash": ........

look my code and error:

and when I executed shows the hash: 0x48b75130d6041d8ff19c063892e77dc4c7e2d5a94049a5a8ab4de6ee054cbc19

all is OK till here, however after waiting some seconds it always breaks and shows an error:

I spend a lot of time, read in every website and there are no solution, how can I solve this issue?

Try the following rawTx data:

var rawTx = {
            "from": fromAddress, // Add this
            "nonce": "0x" + nonces.toString(16),
            "gasPrice": web3.utils.toHex('20000000000'),
            "gasLimit": web3.utils.toHex('21000'),
            "to": contractAddr,
            "value": "0x0",
            "data": dataso,
            "chainId": 1 // For mainnet // Use 3 for ropsten testnet
        };

Keep in mind that the private key should be of the fromAddress

EDIT AFTER HAVING A LOOK AT YOUR SMART CONTRACT:

I observed that your decimals is 3 (in your smart contract) and you're converting your value upto 18 decimals (le18) but what you need is le3.

So changing this variable dataso like this may help:

var dataso=myContractes.methods.transfer(destinityAddr,web3.utils.toHex(1e3)).encodeABI();

  • Thank you for your help! well i did different tests but the error still appear after send signedTransaction, i can see that it happens only when i tried to send tokens from one specific contract, but i can send other tokens without problem, maybe this issue is from the smart contract? and also it only happens with my code, because if i use metamask or myetherwallet to send this specific tokens all is ok, and don't show any error – sneg Nov 29 '18 at 13:09
  • I just checked your txn hash and I found that you are sending 1000000000000000000 tokens which you don't have and that is the reason your txn is failing. I also checked your smart contract and you've given decimals = 3 but while sending you're sending with decimals = 18:web3.utils.toHex(1e18). So instead send like this: web3.utils.toHex(1e3) in your dataso variable – Harsh Nov 29 '18 at 15:30
  • yes ! Exactly ! it was the error, how can i forgot about that decimals are not 18 as other tokens !!! Really Thank you so much for your time and help ! – sneg Dec 1 '18 at 11:58
  • i can't vote yet because i need 15 points, when i have 15 points immediately i will vote positive for your helping commentaries – sneg Dec 1 '18 at 12:00
  • Your welcome! Keep coding and keep helping. – Harsh Dec 2 '18 at 8:26

I have the same issue and found that there may be a bug in web3 or I miss smth: https://github.com/ethereum/web3.js/issues/2587

I did a workaround for it:

  const promiseEvent = ethProvider.sendSignedTransaction('0x' + serializedTx.toString('hex'));
    return promiseEvent
        .on('transactionHash', (txHash) => {
                return onTxHash(txHash);
            }
        )
        .on('confirmation', (confirmNumber, receipt) => {
                logger.info({ ethereumTransactionConfirmed: { confirmNumber, receipt } })
                return onConfirm && onConfirm(receipt, confirmNumber);
            }
        )
        .on('error', (error => {
                // Workaround to for a web3 issue that emit error event while tx was successful
                const reverterErrorMsg = 'Transaction has been reverted by the EVM:';
                if (error.message.startsWith(reverterErrorMsg)) {
                    const receiptString = error.message.slice(reverterErrorMsg.length);
                    const receiptJSON = JSON.parse(receiptString);
                    if (receiptJSON.status === true) {
                        return;
                    }
                }
                logger.error({ ethereumTransactionError: error });
                return onError && onError(error);
            })
        );
