I run ganache, truffle and metmask. If I run the code below I get an error on the this.web3.eth.sendSignedTransaction() function:

EDIT: changed my code to the following.. Error remained the same though.

    const encoded_tx = this.contract.methods.createCountry("NL", 100, 100, 100000000, this.account).encodeABI();
    const nonce = await this.web3.eth.getBlockTransactionCount(this.account);
    const rawTx = {
        nonce: this.utils.toHex(nonce), 
        gasLimit: this.utils.toHex(3000000),
        gasPrice: this.utils.toHex(this.utils.toWei('20', 'gwei')),
        data: encoded_tx,
        from: this.account,
        to: this.contractAddress

    let tx = new Tx(rawTx);

    let serializedTx = tx.serialize();
    this.web3.eth.sendSignedTransaction('0x' + serializedTx.toString('hex'))
    .on('receipt', console.log);

The error is the following:

index.js:2178 Error: Returned error: {"id":6,"jsonrpc":"2.0","error":{"code":-32603}}
at Object.ErrorResponse (errors.js:29)

I have absolutely no idea where to look anymore and feel like I've tried everything, might it have anything to do with the fact that I'm connected to metamask? When I try to send this transaction through metamask with eth.method.send() the transaction does not give an error and behaves as expected.

  • One way to investigate this is to open Ganache Core source code and search for -32603 (or more precisely, the hexadecimal representation of 2^32 - 32603). – goodvibration May 18 '18 at 8:48
  • Thanks for your quick response but this does not seem to get any hits: github.com/trufflesuite/ganache-core/… – jasper May 18 '18 at 8:53

    After doing some research I found out that the error code only means that it's an internal json-rpc error, which isn't helpful at all. – jasper May 18 '18 at 9:05
  • It is. I don't use ganache, but I assume you have to open specific librairies no? Check if RPC allows the connection to use the librairies you use (web3, web3.eth, etc) – Florian Castelain May 18 '18 at 10:56
  • I think Ganache might not support sendSignedTransaction yet.. I've created an issue – jasper May 18 '18 at 12:27

To get the nonce you have to call web3.eth.getTransactionCount, and not getBlockTransactionCount.

  • getTransactionCount

    Get the numbers of transactions sent from this address.

  • getBlockTransactionCount

    Returns the number of transaction in a given block.

To debug interactions with ganache you can start with ganache-cli --verbose it will show the interactions between the client an ganache and show more details about transactions.

  • wow, I can't believe that was it. Thank you so much! – jasper May 18 '18 at 14:22
