HTTP request: %w

Error message

HTTP request: %w

What it means

Transport error in MinerUCloudReader.applyUploadURLs: the SSRF-safe HTTP client's Do() for the /file-urls/batch POST failed. The %w wraps the network cause (DNS, timeout, TLS); it fires after the request was built and signed, distinguishing network failure from the API-status and decode errors handled below.

Solutions

1. Check network reachability to the MinerU Cloud API
2. Verify the configured base URL and SSRF client settings
3. Retry; transport failures are typically transient
