Not working with Polkadot Bulletin Chain

[josepot]

I wanted to try something on the recently deployed Polkadot Bulletin chain. However, chopstick crashes when trying to author a new block:

[18:15:41.731] ERROR (txpool): build block failed
    app: "chopsticks"
    error: {}
[18:15:41.731] ERROR (txpool): build block failed
    app: "chopsticks"
    err: {
      "type": "Error",
      "message": "Unresolved function `env`:`ext_transaction_index_renew_version_1`",
      "stack":
          Error: Unresolved function `env`:`ext_transaction_index_renew_version_1`
              at call (/Users/josep/Projects/runtime-checks/node_modules/@acala-network/chopsticks-core/dist/esm/blockchain/block.js:258:35)
              at processTicksAndRejections (native:7:39)
    }

Minimal repro:

import { ChopsticksProvider, setup } from "@acala-network/chopsticks-core";

const chain = await setup({ endpoint: "wss://rpc.interweb-it.com/bulletin" });
await chain.api.isReady;

const innerProvider = new ChopsticksProvider(chain);
await innerProvider.isReady;

const result = await innerProvider.send("dev_newBlock", [], false);
console.log({ result });

I'm guessing that it's b/c there must be something about the way that the Bulletin runtime authors the blocks that's not compatible with Chopsticks... Could you please look into this? 🙏

you can pass allowUnresolvedImports: true to setup and that should get it running, until such host call is called, which then it won't be able to handle such host call

looks like it is using this
https://github.com/paritytech/polkadot-sdk/blob/dc5d51583212c1792d4bcd7b19c7d05b3946d9ec/substrate/primitives/io/src/lib.rs#L1500

called from
https://github.com/paritytech/polkadot-bulletin-chain/blob/7897e1b1a2befb6f80949e700ba5a7d52c6ba79d/pallets/transaction-storage/src/lib.rs#L353

and it is not one of the supported host call by smoldot
https://github.com/smol-dot/smoldot/blob/98c41cd95128dd8a9de09917bb2017ea8c259d52/lib/src/executor/host/functions.rs#L57

so we need smoldot to support such host call and then we can implemented in chopsticks
