create poll request: %w

Error message

create poll request: %w

What it means

HTTP client error in PaddleOCRVLCloudReader.pollJob: constructing the GET poll request for the job status URL failed at http.NewRequestWithContext. The %w keeps the net/http cause; it fires inside the polling loop after the cancellation guard passed, before the request is sent.

Solutions

1. Check the base URL and job ID form a valid URL
2. Log the composed polling URL
3. Retry the Read flow if the URL config is corrected
