+1 vote

Hi I am new to Blockchain, I tried making transaction using ropsten network, but I m getting error in my web3.js

enter image description here

exports.sendTransactions = () => {

      var admin = "0xEF9dE245F335e0f3ae8A9563FD54D001de1d3E2D";
      var contract_address = "0x39E2f0E87027093C6Ffe76A4d2f20AEE479E5f64";
      var tx = {
        from: admin,
        to: contract_address,
        gas: 184000,
        data: "",`enter code here`
        chainId: "1337"
      web3.eth.accounts.signTransaction(tx, 'privateKey').then((hash) => {
        web3.eth.sendSignedTransaction(hash.rawTransaction).then((receipt) => {
        }, (error) => {
      }, (error) => {

 { messageHash: '0x15e3f440015b35151c1343fb9a6be2497c082b47dbce607d32e80c10eff800f1',

      s: '0x51b096eb07f73d5a30757300caf990b4083d001d2f6aea0fca280aafbea5593d',
      rawTransaction: '0xf8678085012a05f2008302cec09439e2f0e87027093c6ffe76a4d2f20aee479e5f648080820a95a04446233885e382fc9f297dc47fe9294be57623341b781eece94ce28b52bec6eda051b096eb07f73d5a30757300caf990b4083d001d2f6aea0fca280aafbea5593d' }

The chain ID for ropsten is 3. The ID you've used(1337) is wrong. Try with chain ID 3 for the ropsten. It'd work

Thanks! It worked!!
Hi, the error occurred to me also. But the difference is that I've already specified the correct chainID in my tx Object. Maybe you know what else could cause the very same error? Thank you.

Hey @Vlad! Are you running it on Ropsten network? If not, you will have to change the ChainID. Here is a list of ChainID for respective networks:

0: Olympic, Ethereum public pre-release testnet
1: Frontier, Homestead, Metropolis, the Ethereum public main network
1: Classic, the (un)forked public Ethereum Classic main network, chain ID 61
1: Expanse, an alternative Ethereum implementation, chain ID 2
2: Morden, the public Ethereum testnet, now Ethereum Classic testnet
3: Ropsten, the public cross-client Ethereum testnet
4: Rinkeby, the public Geth PoA testnet
8: Ubiq, the public Gubiq main network with flux difficulty chain ID 8
42: Kovan, the public Parity PoA testnet
77: Sokol, the public POA Network testnet
99: Core, the public POA Network main network
7762959: Musicoin, the music blockchain

If this is not the case, then please share your code so that we can have a look at it and see what went wrong. And also share your error log.

Thanks for response, @Omkar :) I'd like to move it to a separate discussion, don't want to post another question with code samples here in comments. Here's the link to my question:

See you there

Did you find a solution for this? I am having same problem
