Error: Not a paymaster contract: unknown account #0

[mattpeskett]

Trying to run a NodeJS script to send a meta transaction for a simple example contract. I've followed the OpenGSN instructions here.

I'm getting the error when trying to initialize a RelayProvider. I'm using the TestPaymasterEverythingAccepted deployed to the Arbitrum Goerli network and I'm using the latest ^3.0.0-beta.9 versions of the @opengsn/contracts and @opengsn/provider packages. I'm passing the web3 provider into the newWeb3Provider function but it fails because there's no account. I'm not familiar with the web3 package and I can't seem to find how to configure it with accounts. I've tried web3.eth.accounts.wallet.add(process.env.PRIVATE_KEY) but that doesn't seem to affect the web3 provider. Any help would be appreciated!

Error

Error: Not a paymaster contract: unknown account #0 (operation="getAddress", code=UNSUPPORTED_OPERATION, version=providers/5.7.2)

My code

Gsn = require('@opengsn/provider');
const Web3 = require('web3');
const Counter = require('../artifacts/contracts/Counter.sol/Counter.json');
async function main() {
    web3 = new Web3(process.env.INFURA_URL);
    chainId = await [web3.eth.net](http://web3.eth.net/).getId()
    const config = {
      paymasterAddress: '0x9dC769B8cBD07131227b0815BEd3526b1f8ACD52',
      loggerConfiguration: {
        logLevel: 'info'
      }
    }
    const provider = await Gsn.RelayProvider.newWeb3Provider({
      provider: web3.currentProvider,
      config
    });
    web3.setProvider(provider);
    //Create a new gasless account:
    user = provider.newAccount();
    counter = new web3.eth.Contract(Counter.abi, '...', {
      from: user.address,
      gasPrice: 0
    });
    //Check current counter value
    const oldCount = await counter.methods.counter().call();
    //Increment count using gasless user
    await counter.methods.increment().send({ gas: 210000 });
}
main()
  .then(() => process.exit(0))
  .catch((error) => {
    console.error(error);
    process.exit(1);
  });

I found that after the release of the beta9 version, the beta9 version configuration cannot be loaded through the network, and the beta8 version was loaded before

config url:https://client-config.opengsn.org/3.0.0-beta.9/client-config.json

I see this message in the logs but I get it for any of the opengsn versions I've tried, including beta 8.

Could not fetch default configuration: Request failed with status code 404

[zhuang-chen0]

In the latest beta9 version, listAccount is called here, and the obtained address is used to build the paymaster contract object, which causes the contract construction to fail. I have been searching for a long time and do not know where to add this account.
