If you are using our server-side libraries for Editor, then I would suggest you use a server-side event. That is how to modified fields for PHP, the .NET and Node.js docs have similar sections.
What is the response from the server? The "system error" message indicates that invalid JSON has been returned by the server - hopefully it will include an error message stating what the issue is. You could also check the PHP error log which will have a warning or error message in it.
What does the server return in that case? You can see it in the network request in your browser's developer tools. Or if you are having problems with it, drop me a link and I'll take a look.

Can show me how I can add 'updated by' with user id when any data table record updated?

I have already modify as below
But it came up with 'A system error has occurred (More information).' when updating a record. What have I done wrong?

I have checked all the log file but can't find any one related.
