index.js:114 Error fetching Aave data: Error: overflow

[deepakA18]

I am implementing lending and borrowing functionality using aave-utilities, but while fetching data using, getReservesHumanized() method, I am getting this error:

provider (using from wagmi):

 const { isConnected, address } = useAccount();
  const { data: walletClient } = useWalletClient();
  const [provider, setProvider] = useState(null);
  const [signer, setSigner] = useState(null);

  // Initialize provider and signer
  useEffect(() => {
    if (walletClient && isConnected) {
      try {
        const Web3Provider = new ethers.providers.Web3Provider(
          walletClient.transport
        );
        const signerInstance = Web3Provider.getSigner();
        setProvider(Web3Provider);
        setSigner(signerInstance);

        console.log("Provider and signer initialized successfully.");
      } catch (error) {
        console.error("Error initializing provider and signer:", error);
      }
    }
  }, [walletClient, isConnected]);

  useEffect(() => {
    if (provider) {
      console.log("Provider is set:", provider);
      fetchAaveData();
    }
  }, [provider]);

My data setup:

const poolDataProvider = provider
    ? new UiPoolDataProvider({
        uiPoolDataProviderAddress: markets.AaveV3Sepolia.UI_POOL_DATA_PROVIDER,
        provider,
        chainId: ChainId.sepolia,
      })
    : null;

  const incentiveDataProvider = provider
    ? new UiIncentiveDataProvider({
        uiIncentiveDataProviderAddress:
          markets.AaveV3Sepolia.UI_INCENTIVE_DATA_PROVIDER,
        provider,
        chainId: ChainId.sepolia,
      })
    : null;

This is what I am doing, I also tried to format the reserves data using formatReserves method in aave-math-utils:

const rawReserves = await poolDataProvider.getReservesHumanized({
        lendingPoolAddressProvider:
          markets.AaveV3Sepolia.POOL_ADDRESSES_PROVIDER,
      });
      
       const reservesArray = rawReserves.reservesData;
      const baseCurrencyData = rawReserves.baseCurrencyData;
      const currentTimestamp = dayjs().unix();

      const formattedPoolReserves = formatReserves({
        reserves: reservesArray,
        currentTimestamp,
        marketReferenceCurrencyDecimals:
          baseCurrencyData.marketReferenceCurrencyDecimals,
        marketReferencePriceInUsd:
          baseCurrencyData.marketReferenceCurrencyPriceInUsd,
      });

      console.log("reserves data:", formattedPoolReserves);

Also I have checked the POOL_ADDRESSES_PROVIDER by comparing it from the aave addresses in the documentation, and eveything is correct.

The issue here is that the Sepolia V3 testnet market is not using the updated Aave v3.2 codebase, which has breaking changes to the view contract functions

This can be resolved by using the LegacyUiPoolDataProvider service, example usage
