Always fails to execute the action, and it responds with 'nothing happens'.

For example, like this.This is from my trial_0.log：

go to cabinet 3
On the cabinet 3, you see a cup 1.
think: I found a cup in cabinet 3. I can use it to clean the plate. Next, I need to put the plate in countertop 1.
OK.
【> take cup 1 from cabinet 3
Nothing happens.】
It seems there is no cup in cabinet 3. Let's try another way to clean the plate.
Nothing happens.
go to cabinet 4
On the cabinet 4, you see nothing.

go to drawer 2
Nothing happens.
go to drawer 2
On the drawer 2, you see a pencil 1.
think: I need to keep looking for the bowl. Let's try drawer 3.
Nothing happens.
【go to drawer 3
Nothing happens.
go to drawer 3
Nothing happens.】

I would like to know if I am doing something wrong, and I would be very grateful if you could help me solve this issue.

I guess maybe the LLM is simulating the conversation itself.The content before "Nothing happens" are all produced by the LLM, but are not the interaction between LLM and the environment.

【> take cup 1 from cabinet 3
Contents above are actually produced by LLM, but it looks like it is the interaction between LLM and alfworld.

No, "No happens" is indeed the result of the environment return, I also encountered this problem, I wonder if you have solved it?

It's been a long time so I may forget how to solve the problem. But you can try check the output of LLM to see if it is in the right format as we wish. The environment return "No happens" means the response of LLM is not in the right format as the code request. You guys can try change to another llm like online stronger ones.
