Summary of Changes

Hello @NarekChang, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly expands the platform's capabilities by integrating the GigaChat language model. It provides users with new nodes for interacting with GigaChat as a chat model, an embedding model, and a general large language model, complete with various model options and API scope configurations. The integration also includes necessary infrastructure for credential management and handling potential TLS certificate issues, ensuring a smooth setup process for GigaChat users.

Highlights

  • GigaChat Integration: Full support for the GigaChat language model has been added, including dedicated nodes for chat, embeddings, and general LLM usage.
  • New Credential Type: A new "GigaChat API" credential type is introduced to securely manage access tokens.
  • Dependency Update: The "langchain-gigachat" npm package has been added as a new dependency.
  • TLS Configuration: A new utility for HTTPS agent configuration is included, along with an .env.example update, to facilitate GigaChat usage with self-signed certificates.

Code Review

This pull request adds support for GigaChat models, including chat, LLM, and embedding nodes. The implementation is comprehensive, but there are a few issues to address. I've found some minor typos in descriptions and a potential issue with how the baseUrl is handled, which could lead to runtime errors. Most critically, there's a significant security vulnerability due to the hardcoded disabling of TLS certificate validation for GigaChat requests, which should be made a configurable, opt-in feature.
