Describe the problem/error/question
Hi guys, how to LM studio to n8n Basic LLM chain. There is no option to choose self hosted model. I have found that I can add OpenAI model, and change the URL to my Self Hosted model. But it’s not working. LM studio gives 200 error. I guess it’s due to there is no API key in credentials
What is the error message (if any)?
I got error 200 on LMStudio side. I guess because I’m using OpenAi node which reqires to add API key, but LMStudio doesn’t require API key.
Please share your workflow
