Describe the bug

Hi everybody,

Is anyone else experiencing a bug with the LLM Agent/Model ChatOpenRouter? Yesterday it was working perfectly fine, but today I noticed it can't parse the API response correctly. I've tried with three OpenRouter models, for example: meta-llama/llama-3.3-70b-instruct:free, and it returns the following error:

Then I tried with google/gemini-2.0-flash-exp:free:

Is this a bug or an update to the source point that has changed the logic of flowise?, Do you know how I can view the trace or debug the API response? Sometimes it only refers to a generic error. I would greatly appreciate it.

Regards,
