openai.types.completion_usage.CompletionUsage() argument after ** must be a mapping, not NoneType

[ywhan2003]

My config2.yaml:

api_type: "openai"  # or azure / ollama / open_llm etc. Check LLMType for more options
model: "gpt-4o"  # or gpt-3.5-turbo-1106 / gpt-4-1106-preview
base_url: "https://api.agicto.cn/v1" 

When I execute the following code, I meet some problems:

async def run(self, instruction: str):
        prompt = self.PROMPT_TEMPLATE.format(instruction=instruction)

        rsp = await self._aask(prompt)

        code_text = SimpleWriteCode.parse_code(rsp)

        return code_text

The problem:

Although I got this same issue, after doing "pip install metagpt --upgrade" this issue was fixed. I recommend you to upgrade metagpt and try again.
