Whenever a new post is published, a pipeline uses AI to write promo copy tailored to four channels β Naver Blog, KakaoTalk, Facebook, and Naver Band β and organizes it in one place. After I added the Band channel, though, only the Band copy kept failing to save for several days.
When I looked into it, the code itself was fine. It was a simple configuration gap: the table where the results are collected had no column to hold the Band copy. I added the column and reprocessed the backlog, and every post was filled in correctly. Because the pipeline was designed to retry failed posts automatically on the next run, recovery was straightforward.
