I have a self-hosted Discourse forum, and I am encountering an Internal Server Error while configuring Discourse AI and the Manual LLMs. How can I resolve this issue? Could you please share any helpful guides to assist me further? Error screenshots [image] Failed to load resource: the server responded with a status of 500 () screenshots Steps performed: [image] [image] [image] [image]

When I unchecked the Enable response API (requires on certain OpenAI Model ) option, the test was successful

Check your /logs route and see if there is more information about the error there. IIRC, Ollama needs something in the API key field, even if not used.

You need to fill all the required fields to run the test. The error you shared happens because you didn’t specify a context window for the model.

Hi @Roman I am facing a new issue. Please find the logs in the above tailing comments and suggest the necessary changes if required, or what could be the reason for the issue.

There you can usually find the latest release notes and documentation related to the latest version.\n\n2. **Check GitHub Repository:** Conan's codebase is hosted on GitHub, so you can also check the repository (https://github.com/conan-io/conan) for releases or tags that correspond to different versions. The repository often includes release notes in the form of commits and pull requests.\n\n3"},"finish_reason":"length"}],"usage":{"prompt_tokens":30,"completion_tokens":200,"total_tokens":230}}
