unsupported protocol data UNSUPPORTED_OPERATION

Describe the Problem

While using the nodejs implementation, resolving a CCIP domain configured with data:uri as a gateway URL throws an UNSUPPORTED_OPERATION exception.

In this example, 0.bensyc.eth is attempting to fetch ENS records from another .eth domain.

However, this does appear to work in a browser, just not with server side nodejs.

Code Snippet

const { ethers } = require("ethers");

infura = new ethers.providers.InfuraProvider("mainnet", {
  projectId: "",
});

async function getDomain() {
  let resolver = await infura.getResolver("0.bensyc.eth");
  resolver.getAddress().then(console.log);
  resolver.getContentHash().then(console.log);
}

getDomain()

Thanks. I’ll look into this shortly. :)

To add support for non-base64-encoded Data URLs, I'll be ripping off the related v6 code. ;)

This has been added in [5.7.1](release: https://github.com/ethers-io/ethers.js/releases/tag/v5.7.1). Try it out and let me know how it works for you.

Thanks! :)
