Developer's retry logic caused duplicate LLM calls due to uncancelled requests

A developer encountered an issue where their retry logic for a slow LLM endpoint inadvertently caused duplicate requests. The problem stemmed from a timeout function that rejected the promise without actually cancelling the underlying network request. This meant the initial slow request continued to process and eventually write to the database, even after a retry was initiated. The fix involved implementing request cancellation using `AbortController` and ensuring the retry also had its own timeout, preventing the original request from completing and writing a duplicate entry.
