exception when run polkadot.

[fntz]

Hello everyone, I want to run polkadot with chain: rococo, but I get an exception:

Thread 'tokio-runtime-worker' panicked at 'Digest item must match that calculated.', /usr/local/cargo/git/checkouts/substrate-7e08433d4c370a21/91061a7/frame/executive/src/lib.rs:467

Full exception is:

Thread 'tokio-runtime-worker' panicked at 'Digest item must match that calculated.', /usr/local/cargo/git/checkouts/substrate-7e08433d4c370a21/91061a7/frame/executive/src/lib.rs:467

This is a bug. Please report it at:

I run polkadot as:

./polkadot --base-path /mnt/volume_fra1_02/rococo --pruning archive --name sync-rococo --rpc-external --rpc-cors all --ws-external --no-telemetry --no-prometheus --in-peers 100 --max-parallel-downloads 25 --out-peers 100 --chain rococo

[bkchr]

Try running with --execution wasm

[fntz]

@bkchr yep, it works. But why the reason ? (just for clarification and understanding)

[bkchr]

We don't take care that much of versioning for Rococo, because it is just a test net that we can restart at any time.

Basically this boils down to a mismatch between the native and the wasm runtime.
