Unable to decoded storage system.events

We setup governance2 testnet, and try to query related records. However, we receive following exceptions.

We depend on substrate's version:

https://github.com/paritytech/substrate?branch=master#37664fe5b3513eb996225f016eceaf74963b8133

You can reproduce the error via the following endpoint

WeightV2 won't be supported until the next API release, it is a WIP in both the API (due for next release in 9.5.1, possibly may have to bump to 10.0.1 since there are non-compatible changes) and the apps UI.

To have it working you current would need to run the master branch of the API (specifically these PRs are needed - #5251, #5254) and this branch of the apps UI, polkadot-js/apps#8193 (which builds on polkadot-js/apps#8191, polkadot-js/apps#8192)

Since the above is for the apps UI, you can track it here - polkadot-js/apps#8188
