When attempting to generate a video using the built-in video_generate tool with Google's Veo models (e.g., google/veo-3.1-fast-generate-preview), the operation immediately fails with a 404 error. The GEMINI_API_KEY is correctly configured and works perfectly when tested with the official google-genai Python SDK. 4. Observe the failure event in the background task: {"error":{"message":"","code":404,"status":""}}

TL;DR

The issue might be resolved by checking the model name and version used in the video_generate tool, as the official Google GenAI SDK uses a different model name ("veo-3.1-fast-generate-preview" without the "google/" prefix).

Guidance

• Verify that the model name used in the video_generate tool matches the one used in the official Google GenAI SDK, which does not include the "google/" prefix.
• Check the documentation for the video_generate tool to ensure that the model name format is correct.
• Test the video_generate tool with a different model to see if the issue is specific to the "google/veo-3.1-fast-generate-preview" model.
• Review the API documentation for any specific requirements or restrictions on model names and versions.

Example

# Official Google GenAI SDK example
from google import genai
client = genai.Client()

operation = client.models.generate_videos(
    model="veo-3.1-fast-generate-preview",  # Note the model name format
    prompt="A test prompt..."
)
print(operation)

Notes

The issue may be specific to the video_generate tool or the OpenClaw version being used. Further investigation into the tool's documentation and configuration may be necessary to resolve the issue.

Recommendation

Apply workaround: Try removing the "google/" prefix from the model name in the video_generate tool to match the format used in the official Google GenAI SDK.
