EVMTraceApi throws `{ invalid: { stale: null } }`

[shunjizhan]

when I try to call evmtraceApi.traceExtrinsic, it throws { invalid: { stale: null } }. It seems like the api didn't skip validity check for the tx, and so marked it as outdated?

For trace runtime api, we probably should skip all these checks, and execute the tx directly

reproduce

first run a chopsticks acala fork, and overrides the runtime with runtime 2250 with tracing

then run the following code, with the latest acala types that already includes types for the trace api

    "@acala-network/api": "^6.1.3-0",
    "@acala-network/types": "^6.1.3-0",

import '@acala-network/types'
import { withAcalaTypes } from '@acala-network/api';
import { ApiPromise, WsProvider } from '@polkadot/api';

async function main() {
  const provider = new WsProvider('ws://127.0.0.1:8000');
  const api = await ApiPromise.create(withAcalaTypes({ provider }));

  // randomly selected evm tx
  const extrinsicHex = '0x41038400421c7a4b5839385d9453cca4dc139f9aba94e426befc5376dde8510b86d8a06803fa61d4950fe1841c7b274262de97c53628ff006da1b007d4bde9cfed6b1f2fdc063efe67b500d983c1602b63cc93ec2a7e3a938db7b0cd72da92a9af2e0650291b000c00820f007fe92ec600f15cd25253b421bc151c51b0276b7d11017b0472f000000000000000000000000000000000000000000000000000000000000000030000000000000000000000000000000000000000000000000000020a3d37de000007b276d2481742d4240000';

  const traceConf = { CallTracer: null };
  const res = await api.call.evmTraceApi.traceExtrinsic(extrinsicHex, traceConf);
  console.log(res.asErr.toJSON()) // { invalid: { stale: null } }

  await api.disconnect();
}

main();
