What is the current behavior and expected behavior?

Current behavior:

When running a substrate-contracts-node locally and navigating to the Contracts tab, this is shown:

Uncaught error. Something went wrong with the query and rendering of this component. Please supply all the details below when logging an issue, it may help in tracing the cause.

Cannot read properties of undefined (reading 'keys')

Expected behavior: I could think of multiple solutions:

• showing an error message explaining what exactly is going wrong
• not showing the Contracts Tab in the menu in case there is an error
• fixing the root cause of the error and showing the Contracts Tab

What is the motivation for changing the behavior?

It would be nice, to not have an uncaught exception displayed anymore :)

Please tell us about your environment:

I setup the contracts-node locally which is mentioned in the substrate smart contracts documentation.

I installed it with:

cargo install contracts-node --git https://github.com/paritytech/substrate-contracts-node.git

I ran it with:

substrate-contracts-node --log info,runtime::contracts=debug 2>&1

• Environment:
  • [ ] Node.js
  • [x] Browser (Chrome, https://polkadot.js.org/apps/#/explorer)

We're able to find a work around or the reason for this issue? We're having it as well :/
