a small script to showcase a buidler-ganache invalid opcode bug

ganache-bug.js

// running `npx buidler run` automatically makes use of buidler-waffle plugin
// => only dependency we need is "chai"
const bre = require("@nomiclabs/buidler");
const { ethers } = bre;
const GelatoCoreLib = require("@gelatonetwork/core");
const { sleep } = GelatoCoreLib;

(async function main() {
  if (bre.network.name !== "ganache") {
    console.error("Test Suite is meant to be run on ganache only");
    process.exit(1);
  }
  // ===== GELATO LOCAL SETUP ==================
  const gelatoCore = await ethers.getContractAt(
    GelatoCoreLib.GelatoCore.abi,
    bre.network.config.GelatoCore
  );

  // DEBUG: buidler-ganache INVALID OPCODE bug

  await gelatoCore.stakeExecutor({ value: ethers.utils.parseEther("2") });

  await gelatoCore.unstakeExecutor();

  await sleep(20000);

  // DEBUG END
})();
