Its tornado problem.

@MiXaiLL76 I simply overwrite the default values when building the image.

Hi, I did the same thing, but a little easier

.jupyter/jupyter_lab_config.py

from tornado import websocket
websocket_max_message_size = 1048 * 1024 * 1024
setattr(websocket, "_default_max_message_size", websocket_max_message_size)
c.NotebookApp.tornado_settings = {"websocket_max_message_size": websocket_max_message_size}
