HTTP 400 when using Google/Gemini API

[Stihotvor]

First of all, thank you for creating such an amazing plugin. I have used it a lot with OpenRouter, LMStudio and Ollama integrations. Now, as Google announced new free models, I would like to test them.

Unfortunately, I can't do it due to HTTP 400 error shown every time I send a prompt to the chat box.

After some investigation, I have found the network traffic tab (Dev Console) and here is what I've seen in the response from Google:

{
  "error": {
    "code": 400,
    "message": "Unable to submit request because it has a stopSequences value of 0 but the supported range is from 1 (inclusive) to 17 (exclusive). Update the value and try again.",
    "status": "INVALID_ARGUMENT"
  }
}

I can't find this parameter in the GUI, so I suppose it should be added on the backend side.

Thanks!
