models/-prefixed IDs before resolving/api/showforwardspayload.modeldirectly intoResolveModel, which only accepts canonical model names or configured aliases. Inputs like"models/deepseek-v4-pro"therefore resolve to not found and return 404, even though they refer to supported models (this exact form is exercised in the added route tests). Any Copilot/Ollama client that sends prefixed model IDs will fail model capability discovery.Useful? React with 👍 / 👎.
