From fe47dd0983204d3359b6f31c9562b030fb3568a6 Mon Sep 17 00:00:00 2001 From: KK Date: Tue, 31 Mar 2026 16:29:02 +0800 Subject: [PATCH] fix: remove hardcoded Google backend_url that caused 404 errors MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The CLI hardcoded https://generativelanguage.googleapis.com/v1 as the backend_url for the Google provider. When forwarded as base_url to ChatGoogleGenerativeAI, the google-genai SDK constructs incorrect request paths resulting in 404 Not Found for all Gemini models. Fix by setting the Google provider's backend_url to None so the SDK uses its default endpoint. GoogleClient.get_llm() still forwards base_url when explicitly provided, preserving proxy/custom endpoint support. Reproducer: ChatGoogleGenerativeAI( model="gemini-2.5-flash", base_url="https://generativelanguage.googleapis.com/v1", ).invoke("Hello") # → ChatGoogleGenerativeAIError: 404 Not Found --- cli/utils.py | 2 +- tradingagents/llm_clients/google_client.py | 6 ++---- 2 files changed, 3 insertions(+), 5 deletions(-) diff --git a/cli/utils.py b/cli/utils.py index 62b50c9c..290a4b67 100644 --- a/cli/utils.py +++ b/cli/utils.py @@ -192,7 +192,7 @@ def select_llm_provider() -> tuple[str, str]: # Define OpenAI api options with their corresponding endpoints BASE_URLS = [ ("OpenAI", "https://api.openai.com/v1"), - ("Google", "https://generativelanguage.googleapis.com/v1"), + ("Google", None), # google-genai SDK manages its own endpoint internally ("Anthropic", "https://api.anthropic.com/"), ("xAI", "https://api.x.ai/v1"), ("Openrouter", "https://openrouter.ai/api/v1"), diff --git a/tradingagents/llm_clients/google_client.py b/tradingagents/llm_clients/google_client.py index 48055560..baa31add 100644 --- a/tradingagents/llm_clients/google_client.py +++ b/tradingagents/llm_clients/google_client.py @@ -28,10 +28,8 @@ class GoogleClient(BaseLLMClient): self.warn_if_unknown_model() llm_kwargs = {"model": self.model} - # base_url is intentionally NOT passed to ChatGoogleGenerativeAI. - # The google-genai SDK manages its own endpoint and API versioning internally. - # Passing a base_url (e.g. https://generativelanguage.googleapis.com/v1) - # causes 404s because the SDK appends its own paths onto the override URL. + if self.base_url: + llm_kwargs["base_url"] = self.base_url for key in ("timeout", "max_retries", "callbacks", "http_client", "http_async_client"): if key in self.kwargs:
