All of the packages referenced are updated to the last version, using node v14.16.1 (npm v6.14.12).
Following along with the files mentioned in the error, it seems like the Provider.isProvider() function from "@ethersproject/abstract-provider" returns false on the web3 provider being passed, causing the error, at this point I guess :

line 629 of @ethersproject/contracts/src.ts/index.ts :
    } else if (Provider.isProvider(signerOrProvider)) {

Hope my description was clear enough

EDIT :
Using the following as a provider, seems to have solved the issue, however it is quite strange :

import {ethers} from 'ethers'
const provider = new ethers.providers.JsonRpcProvider('http://localhost:9545');

@royce777 this library, uses the ethers.js stack, since the latest major version.

Since you seem to be approaching this from the web3 angle, consider using Web3Provider from ethers.js to wrap your provider.
Also, please take a look at https://docs.ethers.io/v5/migration/web3/#migration-from-web3-js

You seem to also have resolved your own issue by using JsonRpcProvider, which is the correct approach if you are connecting through JSON-RPC.
As you probably know already, you can also use rpcUrl directly in the config if you're not manipulating the provider properties.

Please close this issue if this solution works, otherwise please add more details about your use-case.
