Video delete is not supported by Vertex AI Veo.

Error message

Video delete is not supported by Vertex AI Veo.

What it means

NotImplementedError from the Veo video-delete transform: the Vertex AI Veo API has no delete operation (Google reaps videos automatically), so both transform_video_delete_request and its response counterpart deliberately refuse to implement deletion.

Solutions

  1. Do not call video_delete with vertex_ai — see error 2265
  2. Skip this method in provider-matrix tests with an allowlist of unimplemented operations
Defensive patterns

Strategy: validation

Validate before calling

if provider == "vertex_ai":
    raise FeatureUnavailable("video delete response transform is not implemented for vertex_ai")

Try / catch

try:
    config.transform_video_delete_response(raw, logging_obj)
except NotImplementedError as e:
    raise FeatureUnavailable(str(e)) from e

Prevention

When it happens

Trigger: Directly calling transform_video_delete_response on the vertex config, e.g. in a custom handler or an exhaustive unit test over provider methods.

Common situations: Custom HTTP handlers assembled by hand; test suites iterating all transform methods per provider.

Understand the failure class

Background: UnsupportedOperationException and "is not supported" errors: when a library deliberately refuses a call — this error's family across 30 libraries.
