Is there a possibility of encountering multiple errors leading to this specific error message?

Despite searching online, it appears that the error occurs in the JavaScript file when getelementbyid returns null. However, after verifying all element ids and confirming their accuracy, I am considering potential issues related to the wizard section in the XML.
One of the main reasons for this issue occurs when Javascript tries to access a property through an array index that does not actually exist. For example, if 'someArray[0].someProperty' is called but there is nothing at index 0 in 'someArray', an error will be triggered.
This problem often occurs when a function is used that is expected to return an array, leading to the assumption that the 0 index exists. This scenario is common in jQuery calls where selector functions return arrays of values, and it is assumed that the desired action should target the first element (index 0).
