Hardhat Counter tests fail with Kurtosis ethereum-package (invariant was violated: receipt should not be null)

[jaa2]

Version of Hardhat

3.1.8

What happened?

Basic Counter tests fail with Kurtosis. Seems like an issue with checking emits. Does not happen with other execution RPC clients.

Running Mocha tests


  Counter
    1) Should emit the Increment event when calling the inc() function
    2) The sum of the Increment events should match the current value


  0 passing (274ms)
  2 failing

  1) Counter
       Should emit the Increment event when calling the inc() function:

When I run more comprehensive tests, Hardhat fills up several blocks with transactions.

Minimal reproduction steps

1. Initialize hardhat with

npx hardhat --init

(Choose Hardhat 3 Beta and ethers + mocha for testing.)

2. Write network_params.yaml:

participants:
  - el_type: geth
    cl_type: lighthouse
    count: 1

network_params:
  prefunded_accounts: '{"0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266": {"balance": "999999ETH"}}'

3. Run Kurtosis:

kurtosis run github.com/ethpandaops/ethereum-package --args-file ./network_params.yaml --image-download always --enclave hh-test

4. Add this network to hardhat.config.ts:

    kurtosis: {
      type: "http",
      chainType: "l1",
      url: "http://127.0.0.1:32003",
      accounts: [
        "0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80",
      ],
    }

5. Run tests:

npx hardhat test --network kurtosis

Output:

$ npx hardhat test --network kurtosis
