Drupal 8 - DataTables wanring (table id = 'datatable'): Cannot reinitialise DataTable

I always get the following error. I press okay and still everything seems to work so far.

DataTables wanring (table id = 'datatable'): Cannot reinitialise DataTable

To retrieve the DataTables object for this table, pass no arguments or see the docs for bRetrieve and bDestroy
I always get the following error. I press okay and still everything seems to work so far. I have seen that Drupal 7 has a patch for this error. There is also a patch for Drupal 8.

In the documentation of the datatables plugin I found the following:

But where to put it. Thanks for your help.

**my datatables.js
**

     /*
       * Support functions to provide a little bit of 'user friendlyness' to the textboxes in
       * the footer
       */
    var asInitVals = new Array();
    
    jQuery(document).ready(function() {
      var oTable = jQuery('#datatable').dataTable({
        paging: false,
        searching: false,
        "oLanguage": {
          "sSearch": "Search all columns:"
        }
      });
    
      jQuery("thead input").keyup(function() {
        /* Filter on the column (the index) of this element */
        oTable.fnFilter(this.value, jQuery("thead input").index(this));
      });
    
    
    
      /*
       * Support functions to provide a little bit of 'user friendlyness' to the textboxes in
       * the footer
       */
      jQuery("thead input").each(function(i) {
        asInitVals[i] = this.value;
      });
    
      jQuery("thead input").focus(function() {
        if (this.className == "search_init")
        {
          this.className = "";
          this.value = "";
        }
      });
    
      jQuery("thead input").blur(function(i) {
        if (this.value == "")
        {
          this.className = "search_init";
          this.value = asInitVals[jQuery("thead input").index(this)];
        }
      });
    });

The code you show seems to initialize Datatables once. There is not enough information to understand why you get the "Cannot reinitialise DataTable" error. In order to help we will need a link to your page or a test case to see what is happening with the page.
