Error When Testing Async Backing Enabling Runtime Upgrade

[Mihajlo-Pavlovic]

We are experiencing an error when trying to test the runtime upgrade which enables syncing on NeuroWeb Testnet.
We get this log on transaction after executing enactAuthorizedUpgrade:

We are using polkadot-v1.11.0 and starting chopsticks with latest tag: npx @acala-network/chopsticks@latest -c neuroweb-testnet

This is the same error as issue #730 which is now closed.

[Mihajlo-Pavlovic]

It looks connected to this issue paritytech/polkadot-sdk#3211, do chopsticks have this fix?

[ermalkaleci]

If you're testing the transition to async backing then it's not supported

[ermalkaleci]

you should try zombienet to test this transition because it depends purely on the client and you need to test your client can do it

[ermalkaleci]

@Mihajlo-Pavlovic this PR will add support but you still need to test the client. Chopsticks only tests runtime
