dingtalk: marshal reply: %w

Error message

dingtalk: marshal reply: %w

What it means

ReplyWithAt wraps json.Marshal failure of the text/at payload before POSTing it to the session webhook. Practically unreachable for a map of strings, but guarded so a marshal anomaly never sends a half-built payload.
