Error when fork Async Backing Enabling Runtime

[sfffaaa]

Hi, we encountered a similar issue: #743. However, the fix doesn't help in our case.

    app: "chopsticks"
                     runtime  ERROR: panicked at /home/jaypan/.cargo/git/checkouts/polkadot-sdk-d4b773be765ce22f/538d3a3/substrate/frame/aura/src/lib.rs:416:9:

Is that related to paritytech/polkadot-sdk#3211?

My command is this

yarn start -e wss://docker-test.peaq.network -w peaq_runtime.compact.compressed.wasm.peaq.v0.0.101

And the WASM code is here

The version of WASM is based on polkadot-sdk 1.7.2

your problem seems to be missing aura runtime api to get slot duration and chopsticks is falling back to 12s block time

[sfffaaa]

Hi, thanks for replying. I'm checking about the aura runtime API (auraApi.slotDuration) and the return is 6000.

In my survey, it looks like this didn't affect after writing, but I don't understand why

[ermalkaleci]

@sfffaaa ok I see. Chopsticks can't find aura storage and assuming there's no aura_runtime_api and it fallback to 12s block time

[sfffaaa]

Yep, you are right. I also found the solution and open the MR

[ermalkaleci]

I have this PR opened. I will apply a fix there

[sfffaaa]

Cool, that will be great! Thank you very much!
