HTTP request: %w

Error message

HTTP request: %w

What it means

Transport error in PaddleOCRVLCloudReader.submitJob: the SSRF-safe HTTP client's Do() for the multipart form POST failed at the network level. The %w wraps the underlying net error; fires after the form was built and the request signed, before status/response handling.

Solutions

1. Check reachability of the configured PaddleOCR-VL Cloud URL
2. Retry; large multipart uploads may need longer timeouts
3. Verify token and endpoint configuration
