How Do I Handle Wan 3.0 Failed Generations?

Overview

Handle Wan 3.0 failed generations as normal product states, not as invisible backend exceptions. Save the request, prediction id, route, settings, status, error response, cost record, retry decision, and support note for every failed job.

Separate failure types before retrying. A malformed prompt, missing file, blocked content, expired asset URL, provider timeout, and user cancellation should not follow the same path. Some failures deserve a corrected input; others need backoff, support escalation, or a clear no-retry message to the user.

Cost handling must be explicit. Store the pre-submit estimate and the final prediction charge so billing questions can be answered from records, not memory. If your product grants retries or refunds, make that rule visible before the user starts high-resolution or long-duration work.

WaveSpeedAI’s Wan 3.0 route uses asynchronous statuses, which lets your app display pending, running, completed, failed, cancelled, timeout, and deleted states cleanly. Build UI copy for each state before launch. A good failure flow keeps trust even when a generation does not produce a usable clip. It also prevents support from guessing what happened later.
