Hi, After many many trials i have to write that new post. I try to add PDFs with instructions and products/services data on VAPI but even following the instructions, VAPI never uses the knowledge in the files. Exemple : Please give me the price of that product name Response : I dont have access to the prices Here is the file https://dashboard.vapi.ai/files/f9b8fdad-849f-4422-aa99-0f1a2576033f I have tried two different assistants, different models, transcribers, i deleted the files and reuploaded it... Among dozens of prompting trials but there has not been any time with an answer based on the files. Please let me know how this works.

@Fabienml Hello! I'm sorry to hear that you're experiencing difficulties with integrating your PDF documents into VAPI. Let's try to troubleshoot this together. Firstly, it's important to ensure that the PDF document you've uploaded contains the information in a format that VAPI can understand and retrieve. Text in the PDF should be selectable and not embedded within images, as VAPI may not be able to extract information from images. Assuming the document is in the correct format, here are the steps we should verify: 1. **Upload Your Documents**: Make sure the PDF is uploaded to the correct section in VAPI's Knowledge Base. 2. **Create an Assistant**: When creating your assistant, ensure that you have selected the document you’ve uploaded in the Knowledge Base feature. 3. **Configure Your Assistant**: Check if the assistant is configured to use the Knowledge Base effectively. This includes setting up intents and entities that correspond to the information in your PDF, such as product names and prices. If you have already followed these steps correctly, there might be an issue with how VAPI is processing the document. In this case, I would recommend reaching out to VAPI's support team with the details of the issue and the steps you've taken so far. They might need to look into the system to identify the problem. If you'd like, I can assist you in reaching out to the support team or guide you through any of these steps again. Please let me know how you would like to proceed!

Hey @Fabienml can you share the call id along with where it was expected to use KB?
