[Bug]: Ran a Python command

[j3TO]

Is there an existing issue for the same bug?

• I have checked the existing issues.

Describe the bug and reproduction steps

Hi, I'm not very knowledgeable about programming and OpenHands in general, so I apologize in advance if there is some easy solution to this or something. I'm trying to make a website, nothing serious, but constantly as the chat bot tries to run “Ran a Python command”, an error (X) keeps popping up and ERROR text everywhere:
No replacement was performed, old_str `<script> and then comes the code it wrote. If he uses “Ran a bash command
“ or “Read/Edited the contents of a file”, everything is fine, the problem is only in Python command.

OpenHands Installation

Docker command in README

OpenHands Version

0.21

Operating System

WSL on Windows

It's possible that it's a bug somewhere, but it's also possible that the model you're using doesn't work very well. So we should figure out and eliminate that possibility first. What model are you using?

openhands works much better with powerful models, like Claude Sonnet 3.5.

@j3TO Just to note, it's normally not a problem that the agent runs commands that give an error: if the model makes a mistake (and they do, all of them!), then openhands gives an error back. The model will receive the error, and has a chance to correct itself next time.

Can you please share the history with the errors?
