This issue occurs when you:

Render something using React
Then, you manipulate DOM rendered by React with external script
Now on the next render cycle(re-render), React doesn't find the DOM node it rendered previously as its already modified/removed by external script

I think this piece of code is the culprit:

    $(document).ready(function() {
      $("#example").DataTable({
        ordering: true
      });
    });

There is a nice article to use JQuery DataTable with React here. You can refer it and try to fix your issue or you can try replacing it with React version of DataTable(Eg: react-table).

Note: Avoid using React and JQuery together. This might create problems in long run.

Is there any solution to modify the dom?

Ganapati V S Over a year ago

Can you elaborate? Modify the DOM using what? React or the external script?

I was getting this error. I moved the code to a portal, all fixed. Thanks

It's 2021, please don't use jQuery

Ganapati V S Over a year ago

There is nothing wrong with using jQuery as long as it serves the purpose.
