Failed to apply inherents error

[green-jay]

Recently we observed that Chopsticks fails randomly but frequently when trying to produce a new block on Asset Hub. The error is Failed to apply inherents

Running with command:

npx @acala-network/chopsticks@latest xcm --relaychain=configs/polkadot.yml --parachain=configs/acala.yml --parachain=confi
gs/hydration.yml --parachain=configs/polkadot-asset-hub.yml

can you provide bit more details on how to reproduce this error? e.g. do you need to send some XCM to trigger it? or some transaction on AH? does it happens every time?

[green-jay]

It doesn't fail every time but maybe every 3rd time or so when sending any TX on Asset Hub. In my case I was sending XCMs to Asset Hub from and to Hydration

[xlc]

can you provide the encoded tx on hydration so I can replay it? tried a few simple one and works for me

[green-jay]

Probably not connected to asset hub, now i sent this transfer Hydration -> Bifrost transfer and same error occured: 0x01010489000b00000000e1f50500000000000000000000000003010200b91f0100d43593c715fdd31c61141abd04a99fd6822c8558854ccde39a5684e7a56da27d00

Seems like you're using you custom configs, can you share those as well?

[green-jay]

Nothing special, sometimes overriden wasm but mostly not even that. configs.zip

[green-jay]

Also another person from our team encountered the same problem many times with vanilla chopsticks
