undefined method `URI' for #<Langchain::LLM::GoogleGemini>

[palladius]

Gem version: 0.15.2 Seems like URI dependency is overlooked for this:

input

llm = Langchain::LLM::GoogleGemini.new(api_key: ENV["GEMINI_API_KEY"])
llm.chat(messages: [{role: "user", content: "What is the meaning of life?"}]).completion

output - should Summarize the text:

irb(main):014> llm.chat(messages: [{role: "user", content: "What is the meaning of life?"}])

@palladius I dropped a fix in. Btw -- the proper syntax for the messages hash is the following:

irb(main):002> llm.chat(messages: [{role: "user", parts: {text: "What is the meaning of life?"}}]).chat_completion
