I have added a file upload button in UI in the left sidebar.
I created a function to use the backend file upload API.
I was getting below error, I am working on it

I think I need to convert the file into a specific format.

Hi @oryx1729,
Please go ahead and finish this!
I have limited experience working with UI integration!
