TimeLock transaction reverted by EVM on release

Support
1

Hi there, I am trying to create a TimeLock smart contract. But my release function always gets reverted by EVM.
I succesfully deployed ERC20 and TimeLock contracts. Transferred tokens from ERC20 tokens creator balanace to ERC20 TimeLock contracts address. The coins are there, time is there, but my transaction always fails when I try to release the tokens. This is my code (all contracts are default code, except for the minting function in ERC20):

async testRelease()

    {

        console.log('releasing...');

    

        let walletTo        = "0x63b095C8fFE3feb0Db3b8Af5704145367Bc65f43";

        let walletKey       = "[REDACTED]";

        let transaction    = this.GameCoinVestingContract.methods.release();

        const block = await this.web3.eth.getBlock('latest');

        const options  = {
            from  : walletTo,

            to      : transaction._parent._address,

            data    : transaction.encodeABI(),

            gas     : block.gasLimit

        };

        let signed  = await this.web3.eth.accounts.signTransaction(options, walletKey);

        let tran    = await this.web3.eth.sendSignedTransaction(signed.rawTransaction);

        //console.log(tran);

        console.log('released');

        return true;

    }

Also tried:


    function release() public virtual {
       /* require(block.timestamp >= releaseTime(), "TokenTimelock: current time is before release time");

        uint256 amount = token().balanceOf(address(this));
        require(amount > 0, "TokenTimelock: no tokens to release");*/

        token().safeTransfer(beneficiary(), 100);
    }

and the transfer coin function which works:

    async transferCoin(walletFrom: string, walletKey: string, walletTo: string, amount: number)
    {
        console.log('Attempting to transfer GameCoin from:' + walletFrom + " to: " + walletTo + " amount: " + amount);
 
        let transfer    = this.GameCoinContract.methods.transfer(walletTo, amount);
        let encodedABI  = transfer.encodeABI();

        var gasPrice = await this.web3.eth.getGasPrice();
        var gasLimit = 2428000;

        var rawTransaction = {
            "from": walletFrom,
            "to": process.env.GAME_COIN_CONTRACT_ADDRESS,
            "gasPrice": gasPrice,
            "gasLimit": gasLimit,
            "data": encodedABI
        };

        let signed  = await this.web3.eth.accounts.signTransaction(rawTransaction, walletKey);
        let tran    = await this.web3.eth.sendSignedTransaction(signed.rawTransaction);

        console.log('GameCoin transfer complete from:' + walletFrom + " to: " + walletTo + " amount: " + amount);
 
        return true;
    }

Any ideas?

You shared a private key in your code. I’ve deleted it. Even if you only use it for testing purposes, avoid sharing it publicly.

Are you manually signing and sending the transaction in this way for particular reason? Otherwise, you should try to use the higher level abstractions in web3.js. You should also try to test using Hardhat and Hardhat Network, which is able to give you stack traces to figure out exactly where your code fails.

You should

I do need to sign transactions with private keys from specific accounts. I am a newbie at this as I just got into studying ethereum so I’m not really sure what I should be using. Tried other higher level abstractions and had more problems than solutions than only using raw web3. Just tried hardhat and everything worked out of a box. Thanks for the hint! The contracts work well in tests.

This seems to work in node too, but once I specify my local geth network I get this on release function:

And it works with hard hat local node: npx hardhat node
