Contract method argument of type contract: Error: invalid address or ENS name

[simeoni3]

Hello guys,

I'm trying to invoke the following solidity function from ethers

(it takes another contract as argument):

  function getReservesData(IPoolAddressesProvider provider) public view override ...

I tried this code:

 const provider = new ethers.providers.JsonRpcProvider(env.network);
 
 const contract = new ethers.Contract(
            '0x...'
            [ ...], // contract json abi
            provider
        );

const poolAddressProvider = new ethers.Contract(
            '0x...'
            [ ...], // pool address provider json abi
            provider
        );

await contract.getReservesData(poolAddressProvider);

I get the following error:

core.mjs:6484 ERROR Error: Uncaught (in promise): Error: invalid address or ENS name (argument="name", value="[object Object]", code=INVALID_ARGUMENT, version=contracts/5.5.0)
Error: invalid address or ENS name (argument="name", value="[object Object]", code=INVALID_ARGUMENT, version=contracts/5.5.0)

Probably I'm missing some key information on how to pass a contract type parameter.

Could you please help me?
Thank you very much.

I didn't know you could pass contract objects like that (I mean I'm actually a noob too haha, so take it with a grain of salt I guess). If you are designing these contracts, could you maybe have a contract interface for the other contract in the contract that has this function, and just pass the contract address as the function parameter, and instantiate the interface in that function for your purposes?

You would declare the interface outside the scope of the contract, I do it above or you can import it from another .sol file to reduce clutter

You cannot pass a contract in as an address in v5; that is a feature available in the v6 beta since Contract implements Addressable, which will use the contract address, but not v5.

You should pass in contract.address instead.

Thank you for your reply.
I managed to make it work providing contract.address
