I hope LLM can reference the source URL when responding to your query. Please add a 'URL' parameter in the metadata of each file. I'm not sure why it doesn't take effect?

The reference file redirect address is not effective. Please take a look and see what the problem is. Thank you

@LZC-G Which module are you using? Why do you want to add a URL to the metadata?

[onestardao]

this is a classic mismatch between metadata injection and response construction.

even if your retriever passes the "url" correctly as part of the metadata, many RAG setups (especially in LightRAG, LangChain, or DIY pipelines) don't propagate that field into the final generation stage — unless you've explicitly added logic in the reranker or response builder.

we’ve tracked this as ProblemMap No.10 and No.12 in our own RAG debugger — and built a fix that ensures metadata like url survives the whole pipeline and appears in the final answer when relevant.

if you’re still exploring options, feel free to ask — happy to share our open pipeline fix.
