CKEditor 'instances' Property Undefined Error: Solution and Explanation

var pdescription; \n\nClassicEditor\n .create( document.querySelector( '#pdescription' ) )\n .then( editor => {\n //console.log( 'Editor was initialized', editor );\n pdescription = editor;\n } )\n .catch( err => {\n console.error( err.stack );\n } );\n\n\n\n for (var i in pdescription.instances) {\n \n pdescription.instances[i].on('change', function() { pdescription.instances[i].updateElement() });\n \n } \n\n\n\nplease find my bug in this code. ckeditor says:\nTypeError: Cannot read properties of undefined (reading 'instances')\nThe error message suggests that the 'instances' property is undefined, meaning that the 'pdescription' object does not have an 'instances' property. \n\nTo fix this issue, make sure that the 'pdescription' object is properly initialized as an instance of ClassicEditor. Here is an updated version of the code that should resolve the error:\n\njavascript\nvar pdescription;\n\nClassicEditor\n .create( document.querySelector( '#pdescription' ) )\n .then( editor => {\n pdescription = editor;\n\n for (var i in pdescription.editors) {\n pdescription.editors[i].on('change', function() { pdescription.editors[i].updateElement() });\n }\n } )\n .catch( err => {\n console.error( err.stack );\n } );\n\n\nIn this updated code, we listen for the 'change' event on each editor instance and call the 'updateElement()' method when the event is triggered.
