Unable to use custom rpcs with chopsticks

[distributedstatemachine]

Description

We are currently try to integrate chopsticks in our dev flow an need to implement these custom rpcs. As we current use 0.9.36 version of the sdk , we compile the node and use the wasm overide flag as advised here.

Unfortunately , chopsticks crashes.

Steps to Reproduce

• clone this repo.
• build the wasm target , `cargo build --release --features "runtime-benchmarks"
• run chopsticks with the following commands : node packages/chopsticks/chopsticks.cjs --config=configs/bittensor.yml --wasm-override=../subtensor/target/release/wbuild/node-subtensor-runtime/node_subtensor_runtime.compact.wasm
• execute this script

const { ApiPromise, WsProvider } = require('@polkadot/api');
const { decodeAddress, encodeAddress } = require('@polkadot/util-crypto');
const {Address} = require('@polkadot/types/interfaces');

// const provider = new WsProvider('wss://dev.chain.opentensor.ai:443');

const provider = new WsProvider('ws://127.0.0.1:8000');
const customConfig = {
  provider,
  types: {
    Balance: 'u64',
    DelegateInfo: {
      delegate_ss58: 'AccountId',
      take: 'Compact<u16>',
      nominators: 'Vec<(AccountId, Compact<u64>)>',
      owner_ss58: 'AccountId',
      registrations: 'Vec<Compact<u16>>',
      validator_permits: 'Vec<Compact<u16>>',
      return_per_1000: 'Compact<u64>',
      total_daily_return: 'Compact<u64>',
    },
    SubnetStakeInfo: {
      hotkey: 'AccountId',
      netuid: 'u16',
      stake: 'Compact<u64>',
    },
  },
  rpc: {
    delegateInfo: {
      getDelegates: {
        description: 'Get delegates info',
        params: [],
        type: 'Vec<u8>',
      },
    },
    subnetInfo: {
      getAllStakeInfoForColdKey: {
        description: 'Get all stake info for a given coldkey',
        params: [
          {
            name: 'coldkeyAccountVec',
            type: 'Vec<u8>'
          },
          {
            name: 'at',
            type: 'Option<BlockHash>',
            isOptional: true
          }
        ],
        type: 'Vec<u8>',
      },
    getTotalSubnetStake: {
      description: 'Get total subnet stake',
      params: [
        {
          name: 'netuid',
          type: 'u16'
        },
        {
          name: 'at',
          type: 'Option<BlockHash>',
          isOptional: true
        }
      ],
      type: 'Vec<u8>',
    },
  },
}
};

async function main() {

    const serializedData = await api.rpc.delegateInfo.getDelegates();

    const delegateInfos = api.registry.createType('Vec<DelegateInfo>', serializedData);
  
    console.log(delegateInfos.toJSON());

}

main()
  .then(() => process.exit(0))
  .catch(error => {
    console.error(error);
    process.exit(1);
  });

Excepted Behaviour

Calls succeeds.

[ermalkaleci]

you can't use runtime with benchmarking feature. it will have benchmark host functions (unresolved method)

[ermalkaleci]

Also your custom rpcs are part of your client and not runtime. You can't use them with chopsticks. Chopsticks itself implements only the base rpcs. You can only use runtime apis from chopsticks.
