Greetings from Syncfusion support
We have validated your query and reproduced it from our end. The issue is due to not received the additional event arguments in the imageUploadSuccess event. We have prepared a sample based on your requirement and also we will correct the documentation from our end and refresh the documentation by Jan 14th .
