🚨 Please Note 🚨

When trying to create a BOT by uploading a file of around 10 bytes, I encountered the following error and was unable to create the BOT properly.

An error occurred during synchronization.
Error sending result: '<multiprocessing.pool.ExceptionWithTraceback object at 0x7fbaa4eb2a10>'. Reason: 'TypeError("cannot pickle '_io.BufferedReader' object")'

Steps to reproduce the behavior:

1. Click "Bot Console"
2. Click "Create New Bot"
3. Create a bot with any name
