Does anyone else have a probkem running

Did you follow this tutorial to setup: https://docs.llamaindex.ai/en/latest/examples/llm/perplexity/?h=perpl ?

If you could share a traceback that will help to understand better.

You get 400 when your request has missing items that are required.
There could be multiple factors for this:

• Perplexity may have updated their API which may not be reflecting on llama-index.
• You may be leaving something while setting up.

Yeah, I followed exactly this

The last update in pplx module is 3 months.

Then there is a high chance that pplx made some changes in their API.
Feel free to look into it if you want and we welcome a PR 🙌

Hey @WhiteFang_Jr

I have made the required changes

How can I test it? I have tested that llm.complete and llm.chat functions work?
