Hi all, new to truffle (v5.4.30) and when I run a test that initializes my contract, it fails with: "intrinsic gas too low".

It compiles fine, but I tried reducing my contract's constructor to only calling the ERC777 constructor, and still get this error.
I tried increasing truffle-config's networks.live.gas and gasPrice, but nothing changed.

The only google results are from a couple years ago, using older versions of truffle. I can run other tests, and this contract's constructor looks simple, so I'm not sure what's wrong here. Any ideas?

I'm still having trouble finding my problem, but using a fresh truffle init, I boiled it down to extending a contract from @openzeppelin/contracts
Here's a gist of my boiled-down contract and migration, any tips are much appreciated:
https://gist.github.com/lwillmeth/8050be839f6baa3e31dbc16500b63d1c

The error goes away if I copy the parent contract out of the library and into contracts/, so maybe this is a syntax mistake on my part? I'm not seeing it, and the contract compiles, but won't initialize.

@lwillmeth

It seems this only happens with @openzeppelin's ERC777 contract. I'm able to extend several of their other contracts without problem.

When writing tests using solidity, how do I access the addresses of the accounts that are setup automatically in ganache? In javascript, they are passed as an array to the test, is there something equivalent I can do in solidity?

I was able to mitigate this issue by doing a combination of OS updates, XCode Command line tool updates, updating npm config set python to python3 after updating python using brew.

Hello all,

Trying to get a basic set up running and I was following along setting up Truffle on Avalanche with these docs:

https://docs.avax.network/build/tutorials/smart-contracts/using-truffle-with-the-avalanche-c-chain/

But when I try to open the console, I get this error:

Error: ProviderSubprovider - specified provider does not have a sendAsync method

I feel like there is something just out of date in the docs, but I'm having a hard time nailing down exactly what's going wrong here.. Anyone able to point me in the right direction?

Truffle v5.4.31 (core: 5.4.31)
Solidity - 0.8.11 (solc-js)
Node v17.3.0
Web3.js v1.5.3

Hello, does anyone know the proper way to import ABI jsons? This minimal example doesn't appear to work:

pragma solidity >=0.8.0 < 0.9.0;

import '@uniswap/v2-periphery/build/IUniswapV2Router02.json' as IUniswapV2Router02;

contract Minimal {

  IUniswapV2Router02 immutable uniRouter;

  constructor(address _uniRouter) public {
    uniRouter = IUniswapV2Router02(_uniRouter);
  }
}

It fails with the following error. It should recognise that IUniswapV2Router02 is a contract right?

Compiling your contracts...

The ABI is from "@uniswap/v2-core": "^1.0.1"

I've also tried importing without as IUniswapV2Router02;. Then I get

Is there a way to get an interface ID in my truffle test?

I can get it from the contract via a function that returns type(<my interface>).interfaceId, but I'm not sure how to build it in my JS test.

@naira_garg_twitter I created a Docker stack that has Truffle, Ganache, and React. You will mostly likely need Ganache to use Truffle. You can checkout the tutorial on the website but it's kinda hard to figure out how to set it up. You can take a look at my get started project here.

Someone got any clue?

@defi_legend_twitter chain id is 1337 and network id is 5777. You should use chain id if you need chain id. In most cases, they are same.

I get the following error when executing truffle migrate --network rinkeby --compile-all:

Error: Client network socket disconnected before secure TLS connection was established
    at connResetException (internal/errors.js:639:14)
    at TLSSocket.onConnectEnd (_tls_wrap.js:1570:19)
    at TLSSocket.emit (events.js:412:35)
    at endReadableNT (internal/streams/readable.js:1334:12)
    at processTicksAndRejections (internal/process/task_queues.js:82:21)

My truffle-config.js contains:

rinkeby: {
  networkCheckTimeout: 1000000,
  provider: () => new HDWalletProvider(mnemonic, `wss://speedy-nodes-nyc.moralis.io/${moralisId}/eth/rinkeby/ws`),
  websockets: true,
  network_id: 4,
  gasPrice: 10e9,
  gas: 10e6,
  skipDryRun: true
}

moralisId is of course the unique ID to resolve my full Moralis Speedy Nodes URL.

This error happened after changing the HDWalletProvider URL from wss://rinkeby.infura.io/ws/v3/${infuraProjectId} which is of course Infura and worked absolutely fine.

However, if I compile the contracts first, and use --compile-none instead of --compile-all, it's fine, but this bloats my pipeline. I've tried adding networkCheckTimeout: 1000000 to the config (as suggested elsewhere, and can be seen above), but to no avail.

What am I missing?

Hi, how can I set the ganache timestamp to my currently timestamp?

I'm getting block.timestamp like 113124
