LangChain finishes incomplete status on LangSmith

Hi, I created LangChain and connected to LangSmith.

Honestly, I’ve done with the vibe coding, don’t know much about the deep structure.

If I try to analyze using LangChain and send it to LangSmith, it gathers well on LangSmith. However, it never finishes, and fall into incomplete status at the end.

There are not useful logs that I can have a look into for this errors.

What can be general issues which can cause this problem?

Here’s the code snippet when I send it to LangSmith

langsmith_manager.log_llm_call(
model=self.chat_model,
prompt=f"프롬프트: {system_prompt[:100]}…",
response=result_text,
metadata={
“function”: “refine_memo”,
“memo_length”: len(memo),
“response_length”: len(result_text),
“response_time_ms”: response_time_ms,
“use_dynamic_prompts”: self.use_dynamic_prompts
}
)

Can anybody give me any comments to fix this issue?
