local-deep-researcher Failed to load assistants

When installing the repo and starting the UI service at https://smith.langchain.com/studio/?baseUrl=http://127.0.0.1:2024 gives an error:

Failed to load assistants Please verify if the API server is running or accessible from the browser. TypeError: Load failed

The documentation endpoint methods work however at http://127.0.0.1:2024/docs

Terminal logs are also OK:

How to fix this?

Ollama is running smoothly and I have the following .env file:

OLLAMA_BASE_URL='http://localhost:11434'                # the endpoint of the Ollama service, defaults to http://localhost:11434 if not set
OLLAMA_MODEL='deepseek-r1:8b'                   # the name of the model to use, defaults to 'llama3.2' if not set

# Which search service to use, either 'duckduckgo' or 'tavily' or 'perplexity'
SEARCH_API='duckduckgo'
# Web Search API Keys (choose one or both)
TAVILY_API_KEY=tvly-xxxxx      # Get your key at https://tavily.com
PERPLEXITY_API_KEY=pplx-xxxxx  # Get your key at https://www.perplexity.ai

This happened to me using Safari. I switched to chrome, that fixed it.

try the disabling adblock or security extensions

It doesn't work

Same here using Firefox on Mac connecting to an instance of ollama-deep-research running locally (but on a different machine) in a Linux VM.

Ollama is up and running and I can reach it from my Firefox. I can also reach the /docs endpoint of ollama-deep-research. Not using any privacy extensions or ad blockers in my Firefox. It also doesn't work in Chrome, but the error message is slightly different: "TypeError: Failed to fetch" instead of "TypeError: NetworkError when attempting to fetch resource".

Try replacing 127.0.0.1 with localhost, at least it works for me. https://smith.langchain.com/studio/thread?baseUrl=http%3A%2F%2Flocalhost%3A2024

Still not fixed, not even firefox works. In some way it first worked halfway (didn't show this error, only when I entered a prompt and searXNG was not able to be reached/connected and I started troubleshooting).

Then everytime I get this error and seemingly nothing works now. I think the installing guidance for docker container is outdated otherwise.

Please try to recreate and fix this error...

EDIT: deployed it using LangGraph Studio method. Docker method does not work.
