Hi, I am Van. I'll be glad to assist you today.
If you are receiving this error when redeeming a reward, they likely run out of stock of that specific reward.
For the time being, I suggest doing your daily activities to accumulate more points while waiting for them to update the rewards list.
In addition, you can also reach out to reward support by using the "Provide feedback" option on your account dashboard or using the link below. With this, the rewards team will be aware of your concern.

Please let me know if you need any further assistance. I will be glad to help.
