Cause (Documented platform behavior): The provider maps gs:// URLs to gcsUri and base64 data to inline bytes; other URLs produce an 'unsupported' warning and are dropped.
Fix status: documented_behavior
Misleading approaches:
- Debugging the prompt when the image was never sent.

Problem details
- Observed symptom
- The call succeeds but produces a text-to-video result that ignores the reference image; only a warning in result.warnings indicates it.
- Context
- Product: Vercel AI SDK (@ai-sdk/google) Component: Google video model image-to-video input Operation: experimental_generateVideo({ model: google.video('veo-...'), prompt: { image: 'https://...', text } }) Affected versions: unknown Environment: unknown Trigger: Supplying the start image as a public https URL instead of bytes/base64 or a gs:// URI.

Proposed fix: [AI SDK @ai-sdk/google Veo] image input given as an http(s) URL is silently ignored: warning 'Google Generative AI video models require base64-encoded images or GCS URIs. URL will be ign
Recommended action: Pass the image as bytes/base64 (or a gs:// URI on Vertex) and check result.warnings in tests.
Option: Download the image and pass bytes [evidence: official_recommended_action]
Steps:
1. Or use a gs:// URI
2. Assert no warnings
Expected: The call succeeds or the failure is handled deliberately.
