"UNSUPPORTED_OPERATION" when using getResolver() on Sepolia Testnet

[zixiang2018]

Hi community,

Context

I am trying to resolve domain names (e.g. alice.eth) on the Sepolia testnet but I keep encountering an error. I realise, probably coincidentally, that alice.eth is able to be resolved to its corresponding addresses on Mainnet and Goerli network but it keeps erroring on Sepolia testnet (error shown below).

Just wondering, could it be that Sepolia testnet does not support ENS? Or are there currently no valid domains on the Sepolia testnet?

Here is my code:

I am trying this on ethers@5.7.2, and I also get the same error on ethers@6.7.1. Hence I dont think it might be due to the ethers versioning

const provider = new providers.InfuraProvider("sepolia"); 
var address = await provider.resolveName("alice.eth"); 

Here is the error I got from provider.resolveName

Error: network does not support ENS (operation="getResolver", network="sepolia", code=UNSUPPORTED_OPERATION, version=providers/5.7.2)

}

Pardon me if this showed a lack of knowledge about the ENS.

Any help will be appreciated 🙇
