python - Creating an addon, what am I doing wrong? I'm trying to make an addon in 2.81 and for some reason I'm getting this error:

register_class(...): 
Warning: 'dp.clear_menu' doesn't contain '_MT_' with prefix &amp; suffix
register_class(...):
Warning: 'dp.ui' doesn't contain '_PT_' with prefix &amp; suffix   


I have no idea what "dp" is. Here's the link to what I have:

I'm using Visual Studio Code to run &amp; test my addon and it got fixed for one of these 3 reasons:


I ran VS Code as an administrator
I reinstalled python (but checked the PATH option)
I installed the ptvsd as done in this video
