Error running JSON-RPC server: Missing nonce

[jeremyjams]

Context

Hello, I'm not able to fork a remote network using edr@0.4.1. For comparison, it was running smoothly with edr@0.3.5.

networks: {
    hardhat: {
        [...]
        forking: {
            url: 'https://bellecour.iex.ec',
        },
        [...]
    },
},

Error

          throw new HardhatError(
                ^
HardhatError: HH604: Error running JSON-RPC server: Missing nonce

curl -X POST --data '{"jsonrpc":"2.0","method":"eth_getBlockByNumber","params":["0x1B000B1", true],"id":1}' https://bellecour.iex.ec/

Nonce is indeed missing in blocks of this (PoA) network.

Thanks for reporting the issue; I'm on it.

I'll add a test to EDR to validate that fetching block from that network works.

I fixed the issue, but we decided not to include a test in our test suite as we can't rely on a reliable endpoint like Alchemy or Infura.

We'll ship the fix ASAP in our next release.
