Need advise in risk due diligence report

I need some advice.
My idea for the workflow of the chatbot is to allow uploading of files of the named company. Than It will message the files and company name to perplexity to do the deep research for risk assessment.
But it seems after I upload the file via chatbot, it somehow unable to find the files.

Workflow

Hi → Chatbot : Name of company, ask to upload whatever files the company can provide to reduce risk → send to perplexity → perplexity : Does the deep research and generate a report and send back to the chatbot.

I am struck at the uploading of file as the chatbot seems to not get the files.

Hi @derek_cheong

please use Allow file uploads in options of Chat node:
