Can't find failed relayed GSN Transaction

Support
1

Hi all,

Im trying to integrate the javascript part of GSN:

  • “@openzeppelin/network”: “^0.2.10”
  • in vanilla Javascript
  • Kovan network.
  • Metamask v 7.7.1, connected to Kovan Network

I took the relay_client_config from your chat app repo, since previously I was getting rejected by the relayer for minimum gas prices.

const gasPrice = 22000000001
let relay_client_config = {
        txfee: 90,
        force_gasPrice: gasPrice, // override requested gas price
        gasPricegasPrice: gasPrice, // override requested gas price
        force_gasLimit: 500000, // override requested gas limit.
        gasLimit: 500000, // override requested gas limit.
        verbose: true
    }
    debugger
    const context = await fromInjected({
      gsn: {
        ...relay_client_config
      }
})

this.depositManager = new this.web3.eth.Contract(depositManagerContractInfo.abi, depositManagerContractAddress)

    this.depositManager.methods.contribute(lendingContractAddress, contributorAddress, amountToSend)
      .send(transactionParameters)
      .on('transactionHash', hash => {
        console.log('transactionHash', hash)
      }).on('receipt', receipt => {
        console.log('receipt', receipt)
      }).on('error', error => {
        console.log('error', error)
      })

So I run this, Metamask ask for a signature, I accept and wait for it, but it fails:

utils.js:57 Setting tx receipt status to zero while fetching tx receipt (reverted relayed transaction with status code 1)

so I’m trying to find the TX and hopefully get a revert message to debug, but I can´t find the Tx hash in Etherscan or web3.eth.getTransactionReceipt()

So I input the block number in Etherscan and:
Captura de pantalla 2019-12-20 a las 18.43.26

So:

  1. Could you tell me please what am I doing wrong or what is happening here?
  2. I wich unit is tx_fee denominated? GWei? I assume this is the amount discounted from my contract balance in RelayHub (topped it up previously with 0.5 KETH on DappTool of your GSN website)

Thanks in advance!

Hi @ethicraul,

Were you able to get this working on ganache-cli?

I can see the transaction on Kovan: https://kovan.etherscan.io/tx/0x909d19020265239d45b4d23af31e7b51af23a51da56d21f6a4f7db8852f0cd32

I would try getting the contract working locally and then on Kovan with a simple React app (or the inverse get vanilla JavaScript to work with a simple Counter contract). https://docs.openzeppelin.com/sdk/2.6/gsn-dapp

Are you able to share your contract?

Hi @ethicraul,

Have you had any success tracking this down?

It appears as though the relayed call reverted in your contract.

Another thing to try is calling the contract directly (not via the GSN) with the same parameters.
