I'm trying to make a minecraft bot, and I set index.js as the main file. It even says so in the server startup config. However, every time I try starting it, it gives me a pop up saying "Your server is looking for a file that doesn't exist", and prompts me to select my "index.js" file. Even after I select it again, it restarts and the issue persists.
