Error al interactuar con el contrato IPoolAddressesProvider de AAVE en JavaScript

Question

Tengo problemas al trabajar con el IPoolAddressesProvider contrato de mi código JavaScript para el protocolo Aave. Estoy intentando crear el IPoolAddressesProvider objeto con el siguiente código: const POOL_ADDRESSES_PROVIDER = IPoolAddressesProvider(0x012bAC54348C0E635dCAc9D5FB99f06F24136C9A); However, it seems that the IPoolAddressesProvider object is not exportable in the Aave protocol node package. This is causing problems for me because I need to use the getUserReserveData(IPoolAddressesProvider, address) function, which requires the IPoolAddressesProvider object as an input parameter. Intenté obtener los datos de reserva del usuario mediante la getUserReserveDatasiguiente función: const beginLiquidateCall = await poolDataProviderContract.getUserReserveData(0x012bAC54348C0E635dCAc9D5FB99f06F24136C9A,0x67c0378c1D14447013CEe84A54c558864b95B157); console.log(beginLiquidateCall); Sin embargo, me aparece el siguiente error: Error: missing revert data (action=call, data=null, reason=null, transaction={ data: 0x28dd2d01000000000000000000000000012bac54348c0e635dcac9d5fb99f06f24136c9a00000000000000000000000067c0378c1d14447013cee84a54c558864b95b157, to: 0x3e9708d80f7B3e43118013075F7e95CE3AB31F31 }, invocation=null, revert=null, code=CALL_EXCEPTION, version=6.7.1) También intenté actualizar la primera variable de SEPOLIA WETH y usé el siguiente código: const beginLiquidateCall = await poolDataProviderContract.getUserReserveData(0x7b79995e5f793A07Bc00c21412e50Ecae098E7f9,0x67c0378c1D14447013CEe84A54c558864b95B157); Pero sigo recibiendo el mismo error. Tengo dificultades para entender el origen del problema. ¿Puede alguien ayudarme a identificar el problema o proporcionarme un código que pueda ayudarme a descifrar los datos e investigar más a fondo? Gracias.

The error youre encountering is due to passing the wrong parameters to the getUserReserveData function. In both Solidity and JavaScript, function parameters are always addresses, not the object itself. Specifically, the first parameter of this function expects the address of an underlying reserve token (such as WETH, USDC, etc.), not the address of the PoolAddressesProvider contract. The PoolAddressesProvider is not a token address, and thats why youre getting a revert error. To resolve this issue, you need to provide the correct token address for the first parameter. In the case of the Sepolia V3 market, you can find the addresses of underlying tokens in the Aave V3 Sepolia market documentation. The documentation, usually located at the bottom of the address table, and the address registry list all the underlying token addresses for this market. Its important to note that all Aave test markets use custom deployments of each underlying token, allowing them to be minted for testing purposes. You can use the Faucet contract also listed in the documentation to obtain these tokens for testing. Make sure to pass the correct token address as the first parameter when calling the getUserReserveData function to avoid the revert error.
