unable to read the HTTP response body

Error message

unable to read the HTTP response body

What it means

Returned by readFile when io.ReadAll on a successfully opened HTTP response body fails mid-stream — connection reset, premature close, or read timeout after the request itself succeeded. Partial content is discarded.

Solutions

1. Retry the fetch; transient connection drops are the usual cause
2. Increase the HTTP client's read/response timeout via WithHTTPClient
3. Check whether the server prematurely closes large responses (content-length mismatch)
