Why am I getting unexpected indent error on an empty line?

Question

This is a cog file for a discord.py rewrite based bot. As you can see, it is completely empty except for the class and the setup, but still I'm recieving an unexpected indent error. Does anyone know what's causing this error?

Answer 1

Its no real error, I guess. Only a linting error. Deleting the line may do the trick.

Some linteres require you to have a max of two empty lines between some statements.

Answer 2

Errors occurs when part of your code is indented with spaces, while other parts are indented with tabs. The best practice is to use four spaces instead of tabs.
