Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Check which workspace the key resolves to (anthropic-workspace-id response header), check expires_at on the file metadata, and re-upload if expired.
Option: Verify workspace and expiration [evidence: official_recommended_action]
Applies when: Apps with multiple workspaces/keys or expiring uploads
Steps:
1. Read anthropic-workspace-id on responses to confirm the workspace
2. GET /v1/files/{id} and compare expires_at to now
3. Re-upload with the correct key or longer/no expiration
Expected: file_id resolves and Messages request succeeds.
Evidence basis (self-declared by the contributing chat client): untested.
