where to get these tasks and what prizes they give

Hello people, how's it going? Merry Christmas to everyone! 🎁🌲

I am having problems with this airdrop mission of #deeplink , I do the task but when I try to verify it, I get the error from the second image... does anyone know what might be happening or can help me with this? Supposedly, the mission is to repost the publication on x, but I do it and the verification fails...
