How to return CKEditorFuncNum?

Question

$funcNum = $_GET['CKEditorFuncNum'] ; is not returning the number.

I tried creating the upload.php for ckeditor uploadimage plugin according to https://stackoverflow.com/a/44553006/8719001 (sorry can't add comments yet)

which includes echo "<script type='text/javascript'>window.parent.CKEDITOR.tools.callFunction($funcNum, '$url', '$message');</script>";

However when I drop images it doesn't work and in the console I get the Response Text which doesn't show any funcNumber:

"<script type='text/javascript'>window.parent.CKEDITOR.tools.callFunction(, 'https://example.com/upload/test.jpg', '');</script>"

I think this might be part of filebrowser plugin? Which I have enabled and also declared $settings['filebrowserUploadUrl'] =

Try to setup config.js insert config.filebrowserUploadMethod = 'form';,if you got CKEditor additional arguments empty,(CKEditor,langCode,CKEditorFuncNum). There are some errors occur, Incorrect server response. and [CKEDITOR] Error code: filetools-response-error.. please refer,https://github.com/ckeditor/ckeditor-dev/issues/1894
