some error occurs on the chain when add NotificationProvider

[viczhangge]

When use the NotificationProvider components, then we call the contract function :

await enterRaffleFee({
                onSuccess: handleSuccess,
                onError: (error) => {
                  console.error(error);
                },

The blockchain occurs the error like this，but it will succeed

Contract call:       Raffle#<unrecognized-selector>
  From:              0xabccd
  To:                  0xabcedeff
 Error: Transaction reverted: function selector was not recognized and there's no fallback function

Is there any conventions to resolve this error

Try to add these two functions in your Raffle.sol

 receive() external payable {}

 fallback() external payable {}
