I'm also seeing a similar issue with the WalletConnect Connector. However, I'm seeing this error when using chains that are defined in my config (mainnet, and sepolia), and I'm connected to them in my Wallet (Metamask Mobile).

The reproduction of this error is very inconsistent, probably related to some interaction with WalletConnect.
