[Bug]: Runtime CmdRun timeout issue. Command execution failed: {"detail":"invalid literal for int() with base 10: \'echo\'"}

[xingyaoww]

Is there an existing issue for the same bug?

• I have checked the troubleshooting document at https://docs.all-hands.dev/modules/usage/troubleshooting
• I have checked the existing issues.

Describe the bug

Sometime cmd execution will get error like this:

02:51:33 - ACTION
**CmdRunAction (source=EventSource.AGENT)**
THOUGHT: I will run the development server again in the background to test the autoreloader:
COMMAND:
python ./tests/i18n/sampleproject/manage.py runserver > server.log 2>&1 &

We should write a test case try to reproduce it, and then fix it.
