Parity 2.2.7 doesn't recognize “registrar” or “eip150Transition” in the genesis file

Question

I am trying to run a Parity client and sync it with a Geth private blockchain. I was able to do it at first, but after adding "constantinopleBlock", "byzantiumBlock" and "petersburgBlock" to the genesis file of the Geth client, I couldn't get a valid genesis file for the Parity node.

I am using https://github.com/keorn/parity-spec to translate the genesis file, but Parity fails to start as it doesn't recognize the values "registrar", "eip150Transition" or "eip155Transition" for example. If I remove them, it fails to validate the first block of the Geth node.

This is the genesis file of the Geth node:

{
  "config": {
    "chainId": 1337,
    "homesteadBlock": 0,
    "eip155Block": 0,
    "eip150Block": 0,
    "eip160Block": 0,
    "eip158Block": 0,
    "byzantiumBlock": 0,
    "constantinopleBlock": 0,
    "petersburgBlock": 0
  },
  "alloc"      : {},
  "coinbase"   : "0x0000000000000000000000000000000000000000",
  "difficulty" : "0x100",
  "extraData"  : "",
  "gasLimit"   : "0x700000000",
  "nonce"      : "0x0000000000000042",
  "mixhash"    : "0x0000000000000000000000000000000000000000000000000000000000000000",
  "parentHash" : "0x0000000000000000000000000000000000000000000000000000000000000000",
  "timestamp"  : "0x00"
}

This is the translated genesis file for the Parity node:

{
  "name": "GethTranslation",
  "engine": {
    "Ethash": {
      "params": {
        "minimumDifficulty": "0x20000",
        "difficultyBoundDivisor": "0x800",
        "durationLimit": "0xd",
        "blockReward": "0x4563918244F40000",
        "registrar": "0x81a4b044831c4f12ba601adb9274516939e9b8a2",
        "homesteadTransition": 0,
        "eip150Transition": 0,
        "eip155Transition": 0,
        "eip160Transition": 0,
        "eip161abcTransition": 0,
        "eip161dTransition": 0
      }
    }
  },
  "params": {
    "accountStartNonce": "0x0",
    "maximumExtraDataSize": "0x20",
    "minGasLimit": "0x1388",
    "networkID": 1337,
    "eip98Transition": 9223372036854775807,
    "gasLimitBoundDivisor": "0x400"
  },
  "genesis": {
    "seal": {
      "ethereum": {
        "nonce": "0x0000000000000042",
        "mixHash": "0x0000000000000000000000000000000000000000000000000000000000000000"
      }
    },
    "difficulty": "0x100",
    "author": "0x0000000000000000000000000000000000000000",
    "timestamp": "0x00",
    "parentHash": "0x0000000000000000000000000000000000000000000000000000000000000000",
    "extraData": "",
    "gasLimit": "0x700000000"
  },
  "accounts": {}
}

I am using: Parity-Ethereum/v2.2.7-stable-b00a21f39-20190115/x86_64-macos/rustc1.31.1

What would be the correct genesis file for Parity?

Thanks!

The converter put the eip*Transition properties into a wrong "params" object - it should look something like this:

{
  "name": "GethTranslation",
  "engine": {
    "Ethash": {
      "params": {
        "minimumDifficulty": "0x20000",
        "difficultyBoundDivisor": "0x800",
        "durationLimit": "0xd",
        "blockReward": "0x4563918244F40000",
        "homesteadTransition": 0
      }
    }
  },
  "params": {
    "accountStartNonce": "0x0",
    "maximumExtraDataSize": "0x20",
    "minGasLimit": "0x1388",
    "networkID": 1337,
    "eip98Transition": 9223372036854775807,
