We ran similar test in our staging environment which has exactly the same prompt and same config, and its working perfectly. Need help urgently thank you.

Hey! To help track down this issue, could you share: - The call ID of the call attempting to pull from the knowledge base

Hi, successful KB is call ID: 235785c7-73ed-485e-b892-70ece33bce5c

Try using this config for your trieve knowledge base:

{
  "knowledgeBase": {
    "provider": "trieve",
    "name": "Enlit Asia 2025 Event Knowledge Base",
    "searchPlan": {
      "searchType": "hybrid",
      "topK": 5,
      "removeStopWords": true,
      "scoreThreshold": 0.3
    },
    "createPlan": {
      "type": "import",
      "providerId": "3839f989-294d-4cb7-852f-771cd5524f64"
    }
  }
}

Thank you will try @Gilang

The problem is, even in Dashboard Vapi, our assistant doesnt read the knowledge base or File we Upload. But strangely, in our other orgs its read. We already try to create new assistant, recreate the knowledge base via api, reupload the file. But assistant not read the file as knowledge base in our problematic Org Id. @ivy

@Shubham Bajaj any chance you can help us with this?

Trieve knowledge base is missing in call id 8a34cec5-e8fc-45fc-b5b0-00ca82a8f3a0

What about this call ID: 7d78aaa4-f556-4515-ae98-e0435f34f64b

It is not present in the configuration in that last id either. Make sure you attach the knowledge base to that account/org and it will be able to reference it in the prompt. Check your tools config to ensure it is in the failing org. You can use GET on the /tools endpoint to verify if its there and a POST to create it when its confirmed that it isn't there.

are you able to see if it is connected to Call ID: cc7cf891-893d-4611-b9c1-cd7635abcf3f

Here is a screenshot of both call ids for your reference. The knowledge base should be attached to the assistant model https://cdn.discordapp.com/attachments/1382208188530692217/1382879252457717912/Screenshot_2025-06-12_at_5.26.52_PM.png?ex=684cc22a&is=684b70aa&hm=ccea0614ed6a0c53e4495e0cc073b99647e8ed51cbcde4ca041a16f9b64c5043&

Hi @Gilang can you please check asap thank you

We use knowledgeBaseId, do we need to attach the knowledgebase json directly to Model Objects? cc @ivy

      "model": "gpt-4o-mini",
      "tools": [
        {

              "type": "request-complete",
              "content": "Thank you and Goodbye"
            }
          ]
        }
      ],
      "messages": [
        {
          "role": "system",
          "content": "\n**System Prompt:..."
        }
      ],

      "emotionRecognitionEnabled": true
    },

No, as long as it meets the following conditions it should function: - the knowledgeBaseId attached to the assistant \- the knowledgeBase exists within the org \- the UUID matches the file UUID on that specific org \- the assistant prompt has instructions to pull from that specific knowledge base by the explicit knowledgeBase name

Unfortunately we solved this issues with radical moves. We create new Org and start from scratch. Its working now. Thanks everyone.

Glad the issue was resolved. Please reach out to us if you have any other questions regarding this issue
