Closes Issue: #1872

Description

Fixes override(true) not clearing the embeds on a message. My assumption is that discord treats null the same way as the field not being present, hence sending an empty array fixes it.

From my testing should this work as providing a Collections.emptyList() does the trick.

I had the same thought, just wanted to make sure that it did.
