[ Ticket Description ]
Participants of "Gift Capture" campaign may encounter "Invalid operation, please check your input again." error while sending the Capture using gift feature.
[ Root Cause ]
The way gift feature work is, it sends an API call to backend and requests backend to send a the Capture to receiver. If receiver accepts the request within 72 hours, the NFT ownership will be transferred. Otherwise, there won't be any ownership transfer happen. With this design, backend plays a role to deliver Captures in a "polite" way, i.e. receivers can decide whether or not they want to receive this NFT. However, because there were too many requests flooded into backend in two hours on 24th December, the gateways' load average was even more than 6K.
[ Solution ]
Scaled the API gateways immediately, and the Capture service should be normal again.
