error in displaying tree view in custom component

I am looking for a skilled developer who can help fix a syntax error in displaying a tree view in a custom JS component. The component is written in Vanilla JS. The tree view display of my option-panel component is not working properly and I don't know why. As soon as I add the attribute isTreeView={true} to my component, it stops displaying data. Unfortunately I can't share the environment on which it is displayed, I can only share the js code, and also show the code in which it works correctly - maybe some javascript expert will see that, for example, the data type is incorrect or something else. [login to view URL] - here I need it to work, <e-cda,-option-panel> which is my custom component, when I add IsTreeView=true, data is not displaying anymore, just empty list like on the screenshot.
 ConfigurationUsage - is the place where IsTreeView attribute working correctly in the same custom component, but there is no table. So in summary, I need someone to let me know what I need to change in my code to make it work. I attached code of custom component as well. Requirements: - Strong understanding of JavaScript and its syntax - Experience with building and troubleshooting custom JS components - Familiarity with tree view implementations - Ability to work independently and efficiently If you have the necessary skills and experience, please submit your proposal and provide details on how you plan to approach the fix.
