No versions found for prompt ID {base_prompt_id}

Error message

No versions found for prompt ID {base_prompt_id}

What it means

After querying the prompt table for all versions of base_prompt_id, no rows came back — the prompt has no stored versions (wrong ID, or the prompt only exists under a different base ID); returned as a 404 from the versions endpoint.
