LangSmith Agent Builder – errors with Gemini

I have been trying to use the Agent Builder having configured Gemini as a custom model with my API key and the required fields. When I subsequently describe the agent I want to build, I get: Error: HTTP 400: {“detail”:“Missing one of AGENT_BUILDER_ANTHROPIC_API_KEY, ANTHROPIC_API_KEY in workspace secrets”}

I have tried this several times with different Gemini model selections. Is there a problem under the hood?
Wish that the built-in model selection wasn’t limited to Anthropic and OpenAI.

Hey! Thank you for flagging this. This isn’t intended, and seems to be a bug with adding custom models. Will look into this and report back when we have a fix!
