I am new to Langflow and I was trying to use Llama2 through Ollama as the model but I am getting the following error:
ValueError: Error building vertex Ollama: ChatOllamaComponent.build() missing 1 required positional argument: 'base_url'

The base url is default on http://localhost:11434/

Hi, I'm no expert in langflow but I had a similar issue. Can you describe your langflow deployment? Are you using docker or running on your local machine? Have you tried to make post requests using postman to Ollama?

• Ollama api: https://github.com/ollama/ollama/blob/main/docs/api.md

In my case it was a network related error, and I was running langflow and ollama in separate docker containers. Nothing that creating a network and running both in the same network can't fix. But I would need more details to tell what could be happening on your side (reference images on the error would be much appreciated).

I bet this is an update that might have changed a bug or any other issue I am not familiar with. I have Ollama running on http://127.0.0.1:11434, which is typical, but yesterday there was an error, at midnight it changed ;). One remark, I am not running the app in a container...

I am running langflow locally on my computer. I have the same problem.
What exactly is the base_url?

same problem here. Trying to run a rag flow using ollama.

my friends,
here is what helped for me:
Bring both container (langflow and ollama) in the same network:

1. create new network "m-net"
   docker network create my-net
2. find container names (last column, withe ollama and docker_example-langflow-1):
   docker ps
3. add first container
   docker network connect my-net ollama
   4.add second container
   docker network connect my-net docker_example-langflow-1
   5.use container name as baseUrl: e.g ‘ollama:11434’ for ollama
   hope that helps.

If you are running Ollama in the taskbar, exit out of it. Then go to terminal and start ollama server. It will work.
