[Bug]: `AgentDelegateObservation` is format as json for `CodeActAgent`

[ryanhoangt]

Is there an existing issue for the same bug?

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

Describe the bug

From the log below, the observation of BrowsingAgent finishing its task is sent to CodeActAgent as json.

This seems to be because of this line: https://github.com/All-Hands-AI/OpenHands/blob/45066f19dcec21b718e1d5dfb0586ae1c3091a90/agenthub/codeact_agent/codeact_agent.py#L156

Current OpenHands version

0.9.3

Installation and Configuration

`make start-backend`

Model and Agent

• Model: gpt-4o
• Agent: CodeActAgent

Operating System

Linux

Reproduction Steps

1. make start-backend
2. On browser type: "go to "All-Hands-AI" github profile and get number of repositories they have"

Logs, Errors, Screenshots, and Additional Context

No response

@enyst This might be the reason for your observation last time. I'm not sure if this is expected and simply modifing the observation above is good enough.

Hmm why is this a bug? Even before the "Message()" implementation, the observation was converted to a LLM-formatted message format?

Edit: ahh, now see what you mean, there's one step missing to retrieve the content from the dict first.
