Describe the bug

I am doing signing of EIP 712 message using Metamask and Coinbase wallet. I connected both using wagmi connectors as well. The signTypedData is working fine when I am on Metamask so I was expecting it will work on Coinbase as well. But when I am trying to sign on Coinbase, its given me this error:

UnknownRpcError: An unknown RPC error occurred.

Details: hashFuncMap[method] is not a function

Link to Minimal Reproducible Example

Steps To Reproduce

1. Click connect with metamask
2. Click sign once connected, the metamask popup will show up with correct message data
3. Disconnect with metamask and connect with coinbase
4. Click sign once connected again, it will show the error

Anything else?

When I am creating the stackblitz, I noticed that it's working fine on wagmi v2.0.0 and viem v2.0.0. When I tried upgrading it to the versions I am using, it starts failing.

Not able to reproduce against latest Wagmi version. This is likely a Coinbase Wallet SDK bug and should be reported upstream if it occurs again.
