The KittyBridge::bridgeNftWithData
function is missing an approve
call to authorize spending of the given feeToken
on behalf of the router client, preventing the transfer of the fees required to send the CCIP message to the destination chain.
Without the approve
call, the contract is unable to authorize the router client to spend the feeToken
, thus preventing the transfer of fees required for the CCIP message. As a result, the intended cross-chain message will fail to be sent, leading to severe disruption of the contract's functionality.
Make an approval to the router client for the fees amount, before sending the CCIP message.
