Error "Input should be a valid string" sending request to API

[gcalabria]

Describe the bug

When I send a request to the API endpoint /api/agents/${agent_id}/config I get the following error:

 File "/Users/gui/wild/ai-prototypes-long-term-memory/MemGPT/memgpt/server/rest_api/agents/config.py", line 92, in get_agent_config
    return GetAgentResponse(
           ^^^^^^^^^^^^^^^^^
  File "/Users/gui/.pyenv/versions/3.11.9/envs/ai-prototype-long-term-memory/lib/python3.11/site-packages/pydantic/main.py", line 176, in __init__
    self.__pydantic_validator__.validate_python(data, self_instance=self)
pydantic_core._pydantic_core.ValidationError: 1 validation error for GetAgentResponse
sources.0
  Input should be a valid string [type=string_type, input_value=UUID('8194051a-3ce9-4bea-9ee9-9581abc1b793'), input_type=UUID]
    For further information visit https://errors.pydantic.dev/2.7/v/string_type

I took a look and the attached_sources variable is a list of UUIDs but the GetAgentResponse expects a list of strings instead.
The question is: should we change the GetAgentResponse pydantic model or simply convert the UUIDs to strings?

[gcalabria]

I've modified the GetAgentResponse to expect UUIDs instead, and it is working fine for me. If you want, I can open a PR

seems to be same as #1664
should be fixed by #1679 when merged
