Met the same problem too.

[lxj22]

Same problem here. It seems that the model can not output with the designed format?

[pedramaghazadeh]

The model has issues with outputting the correct format sometimes (Thoughts, actions, and values). In my experience, the issue arises whenever model continues to output random words after successfully answering a question, which ruins the format that is used to extract the tool that needs to be used.
Solution
In my case, adding "###\n", "\n###", and couple of other strings to the stopping criteria helps with token generation and the output will be usable for the pattern matching regex to extract the correct tool.
