failed to create request: %w

Error message

failed to create request: %w

What it means

HTTP client error in BaiduProvider.buildRequest: http.NewRequestWithContext could not construct the POST to the Baidu search endpoint after the body was marshaled. The %w wraps the net/http cause; it bubbles up through Search as a request-construction failure, prior to any network activity.
