Unhandled Rejection (Error): call revert exception (method="balanceOf(address)", errorSignature=null, errorArgs=[null], reason=null, code=CALL_EXCEPTION, version=abi/5.0.10)

Getting a lot of like the above and trackback isn't useful since it is async. This happens a lot and I can't pinpoint what the issue might be, is there a way to better log this?

Thanks for your work

Can you include more information? What contract you are calling, network, etc. What parameters you are passing?

You can use .catch or try..catch with await.

I need more to go on though. ;)

sure, I don't have a balanceOf call anywhere, so it must be my Symfoni hardhat plugin that is calling it. If I change the network from mainnet to my local hardhat node, I get a similar error but now for isApprovedForAll call inside of my code (unlike symfoni).

If I use try catch, I will get the same error, though, right? :)

[nazariyv]

when I log the isApprovedForAll call, I can that the addresses are correct, that the contract is instantiated correctly with my metamask provider and me as the signer.

caught with try catch:

rror: call revert exception (method="isApprovedForAll(address,address)", errorSignature=null, errorArgs=[null], reason=null, code=CALL_EXCEPTION, version=abi/5.0.10)

not much to go off of that. When I look at local node, no errors either

[ricmoo]

I don't make any implicit calls to .balanceOf or .isApprovedForAll. Perhaps there is a bug in your plugin or hardhat?

I don't think this is an ethers issue though... If you open issues against the other projects though, please link back to here so I can keep an eye on it. :)
