It isn't safe to expose RPC publicly without a proxy server that filters available set of RPC methods.

Hey @yrong ! Thanks for reporting this.

It seems that in the past, because we passed the para_id through the chain spec, AH-westend-local started fine with polkadot-parachain, which was able to infer the para id from the chain spec. Now, after introducing the GetParachainInfo, not configuring the asset-hub-westend-local genesis config with a patch for parachain_info pallet here: http://github.com/paritytech/polkadot-sdk/blob/master/cumulus/polkadot-parachain/src/chain_spec/asset_hubs.rs#L38, like we do for asset-hub-rococo-local for example here: https://github.com/paritytech/polkadot-sdk/blob/master/cumulus/polkadot-parachain/src/chain_spec/asset_hubs.rs#L101-L105, results in a node startup failure.

This should be an easy fix, will open a PR on polkadot-sdk and merge it in master soon. Will keep you posted.

[iulianbarbu]

Ouch, it is a bigger miss. The PR missed to implement GetParachainInfo for asset-hub-westend runtime too: https://github.com/paritytech/polkadot-sdk/pull/8651/files#diff-a3b656e8095fe815cf8611c8319aff7b2f32482cdbe7c24ac37a2ce45235f32d. I did it only for rococo. 🙈 My bad, will fix that too.

Thanks for the update @iulianbarbu 🙌

[iulianbarbu]

Opened paritytech/polkadot-sdk#9201.

[iulianbarbu]

There is a slight overlap with: paritytech/polkadot-sdk#9191. We'll probably merge both (since 9191 is a subset of 9201).

Hey @yrong , can you give it a try now? The GetParachainInfo trait impl for AH-westend was added into master. I think you zn network assethub node should start fine, but if not, let us know.

[yrong]

can you give it a try now?

Checked with the recent master, and the issus is resolved. Thanks for the fix!
