Developer fixes silent Gemini TTS batch hang by adding per-request timeouts
A developer building a text-to-speech batch pipeline using Google's Gemini TTS discovered that stalled network connections never threw errors, causing the entire job to freeze indefinitely without triggering any retry logic. Because the socket remained open without failing, the exponential backoff mechanism was never activated, leaving the process alive but doing no work. The root cause was that awaited network calls had no upper time limit, meaning a hung connection could hold the pipeline hostage forever. The fix was a single architectural change: wrapping every network call in a race against a 180-second timeout, so a stall is converted into a catchable error that triggers normal retry-and-backoff recovery. After the change, previously indefinite freezes resolved automatically, and the batch pipeline became self-healing without manual intervention.
