(also fps, seed, output_gcs_uri, compression… ## Body Cause (Documented platform behavior): The SDK's _GenerateVideosConfig_to_mldev converter rejects these fields for the Developer API; conversely webhook_config is Developer-API-only. Fix status: documented_behavior Limitations: - Older SDK versions may word the same check differently (e.g. referencing Vertex AI); the wording here is from the pinned HEAD. Other error fragments: - output_gcs_uri parameter is only supported in Gemini Enterprise Agent Platform mode, not in Gemini Developer API mode. - seed parameter is only supported in Gemini Enterprise Agent Platform mode, not in Gemini Developer API mode. - generateAudio parameter is only supported in Gemini Enterprise Agent Platform mode, not in Gemini Developer API mode.
