[Bug]: RepoExplorer throws AttributeError

[li-boxuan]

Is there an existing issue for the same bug?

• I have checked the troubleshooting document at https://github.com/OpenDevin/OpenDevin/blob/main/docs/guides/Troubleshooting.md
• I have checked the existing issues.

Describe the bug

I was testing this task with GPT-4-turbo:

poetry run python ./opendevin/main.py -i 10 -t "Write a shell script 'hello.sh' that prints 'hello'." -c "Manager" -d "./workspace"

The manager agent attempts to delegate the task to RepoExplorer, but an exception is thrown:

File "/Users/liboxuan/workspace/OpenDevin/opendevin/controller/agent_controller.py", line 181, in start_delegate
task = action.inputs.get('task') or ''
^^^^^^^^^^^^^^^^^
ERROR:root:<class 'AttributeError'>: 'list' object has no attribute 'get'
