Solutions

1. Inspect the raw provider response to see which field carries the generated images and update the transport parser accordingly.
2. Retry the request; some providers intermittently return empty result sets under load.
3. Check the provider dashboard for content-filter rejections that yield a success status with no URLs.

Example fix

Map the provider's result field correctly, e.g. imageUrls: data.output.results.map(r => r.url), instead of assuming data.images.

When it happens

Trigger: The provider invocation completes successfully but yields an empty image URL list — either submit.imageUrls === [] or poll() resolves with [].

Common situations: Typical when content moderation blocks the generation or the vendor returns a degraded success response while still charging. The handler records the invocation with imageCount=0, then fails the job rather than reporting a silent zero-image success.
