smartcontractkit / truffle-starter-kit Goto Github PK

I'm facing an error when I'm trying to execute fund-contract.js. I'm not sure if I'm using some incompatible version of Truffle or so. The deployment worked like a charm.

npx truffle exec scripts/fund-contract.js --network kovan

Error:

Funding contract: 0x1123c6967701ab4a86f7781Fa4E3091383314121
Transaction: 0x0e5447b9f367d76a0bc4c6b9683d4e8d8f7e49c28dc4aeac07ed2e11c0e80d91 exited with an error (status 0) after consuming all gas.
     Please check that the transaction:
     - satisfies all conditions set by Solidity `assert` statements.
     - has enough gas to execute the full transaction.
     - does not trigger an invalid opcode by other means (ex: accessing an array out of bounds).

This is what I see at Etherscan.

Do you have any idea what I'm doing wrong? 🐻 with me 🙂

Steps:

1. npm install truffle -g
2. mkdir myChainlinkProject
3. cd myChainlinkProject
4. truffle unbox smartcontractkit/box

Big, bold, tell users not to do it

The example provided in the README does not work when deploying to dev / cldev (localhost), as there is no Chainlink node on localhost.

Testing on mainnet is prohibitive expensive.

Updating truffle-config.js and README.md to use kovan testnet , as well as adding a note that it will not work on localhost without deploying a Chainlink node to localhost, would help to avoid time consuming efforts by new users.

1. VRF doesnt work with the current truffle box (needs solc v 0.6.6)
2. Upgrade contracts to v0.6 of solidity
3. Fix the fund-contracts script - right now it just hangs due to some recent changes of metamask

When I run

npm test

I get this error

The error comes from some @openzepplin node modules that specify "pragma solidity ^0.8.0". I was wondering if I was doing something wrong or if the repo needs to be updated somehow.

We can import from the @chainlink/linktoken instead.

When trying to run truffle unbox smartcontractkit/box

I have the following error:

I was able to unbox other boxes such as react.

From https://github.com/smartcontractkit/truffle-starter-kit#deploying-contracts:

"This section of the file is where you define which networks you want to interact with. You can read more about that whole file in the Truffle documentation.."

The link is dead. I assume the link should be this?:

After unboxing the Truffle Starter kit and installing dependencies with npm, migration of MyContract.sol fails.

Hi team,

I've been struggling for days to be able to install the dependencies for this starter kit.
Whenever I run the "npm install" command right after successful unboxing I get the following error:
`npm ERR! code 128
npm ERR! command failed
npm ERR! command git ls-remote ssh://[email protected]/ethereumjs/ethereumjs-abi.git
npm ERR! fatal: Could not read from remote repository.
npm ERR!
npm ERR! Please make sure you have the correct access rights
npm ERR! and the repository exists.

npm ERR! C:\Users\Mariano Collarte\AppData\Local\npm-cache_logs\2021-05-12T01_02_24_897Z-debug.log
`
I've setup the ssh account in my github profile and checked connection. This repository seems to be deprecated so I'm not sure why it is pulling it however the npm install fails and the node_modules folder is not being created.

Any help you can provide would be awesome!

Thanks

Hi

I follow your tutorial to create Truffle project with truffle-starter-kit Truffle, Hardhat, and Defi - Chainlink Hackathon Workshop.

I cannot continue doing any next steps due to Unbox failed as the figure shown below.

My environment are belows.

1. Window 10 enterprise
2. Visual studion code , use cmd as terminal
3. Node.js 14.17
4. Truffle 5.3.7
5. Already git app, ghit bash

When running ./scripts/fund-contract.js using truffle exec, the transaction is returned to the callback function where an error is supposed to be returned. This means that the script is reporting an error even under successful execution, example:

/chainlink # truffle exec scripts/fund-contract.js --network cldev
Using network 'cldev'.

Funding contract: 0xa8B323695d987DdE23F63e6B4500FBc84Cd3cd4e
0x3d210eb43710fe4d777a08d871bde9f7bf63b95014c346275a1d203693f2afd9
Truffle v5.2.3 (core: 5.2.3)
Node v10.24.0
/chainlink # echo $?
1

Line 20 here: https://github.com/smartcontractkit/box/blob/master/scripts/fund-contract.js#L20 uses the callback function to return a transaction ID, although according to https://www.trufflesuite.com/docs/truffle/getting-started/writing-external-scripts this should be used for error reporting

Issue

In fund-contract.js when running npx truffle exec scripts/fund-contract.js --network live after successfully migrating(deploying) the default contract MyContract.sol, the contract will hang at const token = await LinkToken.at(tokenAddress); due to what is believed to be metamask changes. See the truffle issue for more information.

Steps to Reproduce

Set up a new Chainlinked project, you can follow the documentation to do this here

mkdir MyChainlinkedProject
cd MyChainlinkedProject/
truffle unbox smartcontractkit/box

Due to the issue with truffle & metamask (mentioned above) you will have to changed one package in package.json:

"@truffle/hdwallet-provider": "^1.0.30", -> "@truffle/hdwallet-provider": "next",
then run:
npm install

Then proceed to set your RPC_URL to interact with the ropsten chain and your MNEMONIC (seed phrase) from your metamask account.

export RPC_URL=asdfasfas
export MNEMONIC='cat dog frog......'

Run the migration script to deploy 'MyContract.sol'

npm run migrate:live

After it is deployed, just run

npx truffle exec scripts/fund-contract.js --network live

After some testing, the output will hang on the fund-contracts file on this line:

const token = await LinkToken.at(tokenAddress);

I was able to get it past this line by adding some pieces of code and a try catch to see the error:

module.exports = async (callback) => {
  try {
    const mc = await MyContract.deployed();
    const tokenAddress = await mc.getChainlinkToken();
    LinkToken.setProvider(process.env.RPC_URL);
    const token = await LinkToken.at(tokenAddress);
    console.log("Funding contract:", mc.address);
    const tx = await token.transfer(mc.address, payment, {
      from: web3.currentProvider.addresses[0],
    });
    callback(tx.tx);
  } catch (error) {
    callback(error);
  }
};

And the error we get is:

Funding contract: 0x64738dc4359739c402fE1523Ff96308DDa47ea5C
Error: Returned error: The method eth_sendTransaction does not exist/is not available
    at module.exports (/Users/patrick/code/demos/truffle/MyChainlinkedProject/scripts/fund-contract.js:20:28)
    at processTicksAndRejections (internal/process/task_queues.js:93:5)
Truffle v5.1.32 (core: 5.1.32)
Node v14.5.0

Expected Behavior

The contract that was deployed during npm run migrate:live will be funded

Actual Results

The script hangs and never completes.

Environment

• Operating System: macOS Catalina 10.15.5
• Ethereum client: Infura
• Truffle version (truffle version): ("@truffle/hdwallet-provider": "^1.0.36") / ("@truffle/hdwallet-provider": "next")
• node version (node --version): v14.5.0
• npm version (npm --version): 6.14.5

This repo needs an overhaul
