@otbutz, thank you for your help in investigating the issue. The root cause is logic to truncate the response data for displaying in monitor info

https://github.com/louislam/uptime-kuma/blob/8c684e92936b5860139b09e50917d55c0b041891/server/model/monitor.js#L551

I have created a new PR to fix those issues (can’t update service name and error when truncating response data)
