Hey I'm running a test where I expect a transaction to throw. Instead of successfully returning a receipt with a status of 0, or throwing a revert error, it throws this invalid JSON RPC response error.

Example:

try {
    // some generic transaction with a contract that should fail via revert or require.
    await promise;
} catch (error) {
    const revertEvent = error.message.search('revert') >= 0;
    assert(revertEvent, 'expected revert');
}

and I get the stacktrace:

Error: Invalid JSON RPC response: {"id":202,"jsonrpc":"2.0"}
