VAPI Knowledge Base Crashed
# support

* I have multiple Knowledge base files Loaded (Which were working perfectly earlier) * I created assistants to summarize knowledge base data - the agent said it has no data * I tried "List Knowledge basee" : https://api.vapi.ai/knowledge-base Response: [] Note: i can see, upload and download knowledge base files successfully @User @User @User @User https://cdn.discordapp.com/attachments/1389757531991314522/1389757532196569088/Screenshot_2025-07-02_at_4.56.26_AM.png?ex=6865c810&is=68647690&hm=8e347d994b3931d31f1a415e31aa2e583e46034d5270f72e2f880d6682e73ad7&

It because Vapi currently now requires you to create a Query Tool linked to your uploaded files and then attach that tool to your assistant, just uploading files is no longer enough..

@User I tried that aswell....it still doesnt work....besides it is supposed to show the list of Knowloedge bases...(that the Query_tool searches through)....but it shows nothing (error 404)

Use Trieve-based knowledge bases to see them via API, or verify your Google-based KB through the Query Tool config and ensure it's linked to a published assistant with the correct org token..

Hey Waqar! The new knowledgebase query tool doesn't create a knowledgebase itself. Instead, it asks you to associate files with it and give it a name. Later, we queries using vector search indexing are searched against the shared knowledgebase files (shared files). This process of performing a vector search on your files is how knowledgebase works currently. When you use the query tool, you're essentially checking for traditional databases or previous database methods knowledge bases. I'll suggest you check out this documentation on how to create a knowledgebase using the query tool and let me know if you have any questions.

I tried that, too. I get an empty list but with HTTP code 200. Anyway, it seems the endpoint 'knowledge-base' doesn't work as expected, or the documentation is unclear. Try using the endpoint 'tool' to list tools. According to Kings_big and Shubham Bajaj's replies, the knowledge base is inside a query tool. I am able to list my query tools and see the knowledge base inside (which has a fileId)
