Im trying to install correctly but the send to server buton dont work. I get 419 error.

In spite of, I can upload images to filemanager directly at the filemaneger url, and later I can load it to the CKEditor through the image information button.

I have:
<meta name="csrf-token" content="{{ csrf_token() }}">

And I have:

<script>
  var options = {
    filebrowserImageBrowseUrl: '{{ asset("/laravel-filemanager?type=Images") }}',
		filebrowserImageUploadUrl: '{{ asset("/laravel-filemanager/upload?type=Images&_token=") }}',
		filebrowserBrowseUrl: '{{ asset("/laravel-filemanager?type=Files") }}',
		filebrowserUploadUrl: '{{ asset("/laravel-filemanager/upload?type=Files&_token=") }}',
	width: 'auto',
    height: 550,
    extraAllowedContent: 'h1;a[!href]' 
  };	
</script>

<script>
CKEDITOR.replace('body', options);
</script>

What is the problem?

    $('textarea[name=offerLetter]').ckeditor({

        filebrowserUploadMethod: 'form'
     });
   </script>

Route:

Route::post('images/upload', 'ImageController@upload')->name('ckeditor.upload');

Create ImageController, then put this method inside it:

public function upload(Request $request)
{
    if($request->hasFile('upload')) {
        $originName = $request->file('upload')->getClientOriginalName();
        $fileName = pathinfo($originName, PATHINFO_FILENAME);
        $extension = $request->file('upload')->getClientOriginalExtension();
        $fileName = $fileName.'_'.time().'.'.$extension;

        $request->file('upload')->move(public_path('images'), $fileName);

        $CKEditorFuncNum = $request->input('CKEditorFuncNum');
        $url = asset('images/'.$fileName);
        $msg = 'Image uploaded successfully';
        $response = "<script>window.parent.CKEDITOR.tools.callFunction($CKEditorFuncNum, '$url', '$msg')</script>";

        @header('Content-type: text/html; charset=utf-8');
        echo $response;
    }
  }
