Laravel ajax store request errormessage, data append to view - ajax

Question

I'm new to ajax and I have two little problems.
With my code I can write the data in the database. I get no error messages and the data are not synonymous directly loaded into the view.
how can I load the data directly into the view without reload the page?
if the privacy is 1, the code should be displayed in the right column, and if the privacy is 0, the code should be displayed in the left column.
How can I output the error messages with my errormessage code?

I believe you have a typo in your ajax backend code; this line to be specific:
$todolists->admin_id = auth::user();
This should be:
$todolists->admin_id = auth()->user()->id;
The typo is generating a Throwable error, which is getting caught by the laravel exception handler and it's detecting that the code is being executed under a ajax request and hence returning a 500 internal server error.
