nothing is written exception when pasting code inside kosmos

[zaibon]

I often get the following error when I'm playing inside kosmos.
It gets trigger when I past a piece of code in the shell and press enter. The error is raised, but it seems the code is still executed.

Unhandled exception in event loop:
  File "/root/.local/lib/python3.6/site-packages/prompt_toolkit/eventloop/utils.py", line 33, in run
    result = self.target()
