Answer a couple of questions to help you:

1. Which version are you running (python/nodeJS)
2. Have you changed the program code
3. What is the version of your minecraft server

As I understand it now, you have an error with the fact that you specified the version of the minecraft server in the program code is not correct.

[thevarunaditya]

Python Nope 1.20.2

A newly created server, without plugins and so on. Only install the game version 1.20.2

[thevarunaditya]

I did it, and I get the same error

[YTFort]

Look, there are two options.

1. This is the case in the bot library. That is, the bot is not ready to work on this version of the game yet. In this case, you just need to wait for the update.

2. This is a bug, to solve it, I will send the code now, try to use it.

[YTFort]

def started(stop):
bot = mineflayer.createBot({
'host': config.get('server', 'host'),
'port': config.get('server', 'port'),
'version': '1.20.2', # If it doesn't help, write 'false' instead of '1.20.2'
'username': config.get('bot', 'name') })
print('Start')

[thevarunaditya]

I will try it when i get home in a few days thank you

I have attempted the above fix, it returns Error: unsupported protocol version: 1.20.2 and likewise Error: unsupported protocol version: false. I am getting the error for protocol version 764 on the JS side of things, too - that's how I found this issue report.

If I'm interpreting the cause of the error correctly, it appears mineflayer itself (a dependency of this project) doesn't yet support 1.20.2, as pointed out by a contributor in an issue there. The issue is still open; so for now, there's nothing we can do except wait for the upstream dependency to be updated for 1.20.2.
