failed to create request: %w

Error message

failed to create request: %w

What it means

HTTP client error in OllamaProvider.buildRequest: http.NewRequestWithContext failed to construct the POST to the provider's baseURL after the JSON body was marshaled. The %w retains the net/http cause; surfaced via Search as request-construction failure before any network I/O.
