Documentation on compatible versions

Hi,

I am running the latest (0.4.0) against the latest polkadot 0.8.27, I am seeing various errors, such as

io.emeraldpay.polkaj.api.RpcException: RPC Exception 1002: Verification Error: Runtime error: Execution failed: Wasmi(Trap(Trap { kind: Unreachable })) (RuntimeApi("Execution failed: Wasmi(Trap(Trap { kind: Unreachable }))"))

Is there a version I should use to ensure compatibility? Any recommendations?

BTW I am using --chain=westend

Thanks, Niall

+1 Indeed there is no ref to what exact version has been target, and as time goes things start breaking, and there is no exact version where it should work
