Given an example:

import {ethers, providers } from 'ethers';

const provider = new providers.JsonRpcProvider("https://cloudflare-eth.com")

var privateKey = '0x00000000000000000000000000000000000000000000000000000000000000d0';
var wallet = new ethers.Wallet(privateKey,provider);

const contract = new ethers.Contract(
  '0xD1E5b0FF1287aA9f9A268759062E4Ab08b9Dacbe',
  [
    {
      constant: true,
      inputs: [
        {
          name: 'tokenId',
          type: 'uint256',
        },
      ],
      name: 'ownerOf',
      outputs: [
        {
          name: '',
          type: 'address',
        },
      ],
      payable: false,
      stateMutability: 'view',
      type: 'function',
    },
  ],
  wallet,
)

contract.functions.ownerOf(
  '0x6d8b296e38dfd295f2f4feb9ef2721c48210b7d77c0a08867123d9bd5150cf47'
).then(console.log, console.log)

It is interesting that the same call to mainnet.infura.io doesn’t produce such error.

It looks like LinkPool (I’ve not heard of that one before) doesn’t return any of the needed data to recreate the actual correct revert data returned, so I don’t think there is anything that can be done for that… 😒

Glad it works for Geth though. I’ll close this issue.

Thanks! 😃

@bogdan Can you try with this request: {"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":83} or provider.getBlockNumber() and check if you are getting latest block numbers on cloudfare like infura as @ricmoo has suggested?
