read response failed

Error message

read response failed: %w

What it means

Wrapped I/O error in GetTopicDetail (plugin/discourse/discourse.go:489): the topic detail response arrived with HTTP 200 but its body could not be fully read (connection dropped mid-transfer, timeout). The JSON was never parsed, so the failure is transport-level.

Solutions

1. Retry the detail request; the cause is usually transient
2. Check network/proxy stability
3. Increase the HTTP client timeout if large responses are truncated

links, err := plugin.GetTopicDetail(id)
if err != nil && strings.Contains(err.Error(), "read response failed") {
    time.Sleep(time.Second)
    links, err = plugin.GetTopicDetail(id)
}

When it happens

Trigger: io.ReadAll(resp.Body) fails after a successful detail request — connection dropped mid-body, truncated chunked encoding, timeout during read.

Common situations: 服务端提前关闭连接；响应体过大超过读取时限。
