⚡ Key issues to review Missing Error Handling The function requestFromNearRpc does not handle network or fetch errors. It is recommended to add error handling to manage cases where the fetch request fails or the network is unreachable. Inconsistent Parameter Usage The function callViewMethod inconsistently uses rpcUrl. It should consistently pass rpcUrl to all calls or handle it differently to maintain consistency and avoid potential bugs. Error Handling The function fetchBalance should handle possible errors from requestFromNearRpc or when balanceString is not present in the response.
