TypeError: Object of type Tag is not JSON serializable

[richlysakowski]

When loading URLs I get this error message. I tried just loading the ThinkRAG webpage.
I got this same error with other webpages.

I am running ThinkRAG locally on Windows 10 Pro, Ollama, Llama3 LLM.

I tried fixing the code after these two errors, but I have not fixed it yet. I will post and synch the solution if I can get it working on my local installation.
