I created an account on vapi 2 days back and created my first Assistant and a workflow. It worked in the afternoon when I tested it once but now it gives the error:

ts
{
    "data": null,
    "error": {
        "message": "Duplicate Assistant Name \"Hannah AI\".",
        "error": "Bad Request",
        "statusCode": 400
    }
}

I am certain I don't have any duplicates. Moreover I tried renaming and using the vapi.start() many times. But it still gives me this error and I don't know what to do. Can someone please guide me!

This error often occurs when there's a hidden assistant with the same name. Try this approach: 1. Contact Vapi Support with your organization ID and the specific error message 2. In the meantime, try using a completely different assistant name with a unique identifier:

ts
// Instead of "Hannah AI"
const assistantName = "Hannah_AI_" + Date.now().toString();

This creates a timestamp-based unique name that should bypass the duplication error.

To help track down this issue, could you share one or two: - The call ID - When exactly this happened (the timestamp) - What response you expected to get - What response you actually got instead This would really help us figure out what went wrong!
