Error when changing networks while using Ethers Adapter

[cryptobredda]

Hi,

I am using the Ethers Adapter to convert the provider and the signer from viem to Etherjs

Currently i am running into an issue where when I change the network from Goeril to any other network, my app gets an error on the chain ID. I have shared an image showing the error.

Could you please guide me on how to fix this?

I am using an exact copy of the code in this link for the converion, I have not change any of the variables or methodology

Further information to help you.

I used the code in the Ether Adapter docs but I am running into an issue when switching networks. It seems like that chainId is defined only for Etheruem and Goeril but not other chains. How do I get it to work for other chains as well.
