[ ] failed to read response on page

Error message

[%s] failed to read response on page %d: %w

What it means

Wrapped read error in panzun's searchImpl (plugin/panzun/panzun.go:144): the 200 response on a given page could not be fully read. If earlier pages already produced results the loop breaks (partial results kept); otherwise this error is returned, meaning the whole search failed on the first page read.

Solutions

1. Retry the request — transient read failures usually succeed on a second attempt
2. Increase the HTTP client/read timeout
3. Check for proxies or firewalls truncating responses
4. Rely on partial-results semantics (later pages already break gracefully)

Example fix

// before
return nil, fmt.Errorf("[%s] failed to read response on page %d: %w", p.Name(), page, err)
// after
if len(allResults) == 0 && retryCount < maxRetries {
    return p.searchImplRetry(client, keyword, ext, retryCount+1)
}
return nil, fmt.Errorf("[%s] failed to read response on page %d: %w", p.Name(), page, err)

results, err := plugin.Search(keyword, ext)
if err != nil {
    if strings.Contains(err.Error(), "failed to read response") {
        // transient I/O error — retry once before giving up
    }
}

When it happens

Trigger: The connection drops or times out mid-body transfer (chunked/incomplete response) while reading the panzun.cc discussions API response on the first page.

Common situations: 翻页较深时连接被服务端断开；响应体过大超时。
