Troubleshooting AI Assistant Not Responding After Initial Message

Last updated: January 26, 2026

If your AI assistant stops responding after the first message or greeting, this is typically caused by a misconfigured tool in your setup.

Common Cause: Incorrect Tool Configuration

The most frequent reason for this issue is when an "API Request" tool has incorrectly configured dynamic parameters. The dynamic parameters must follow a specific JSON schema format.

How to Fix API Request Tool Configuration

For API Request tools, ensure your dynamic parameters follow this correct schema format:

{
  "type": "object",
  "required": ["values"],
  "properties": {
    "values": {
      "type": "array",
      "items": {
        "type": "string"
      },
      "description": "A list of values"
    }
  }
}

Troubleshooting Steps

  1. Review all your configured tools, especially any API Request tools

  2. Check that the dynamic parameters in each tool follow the correct JSON schema format

  3. Look for examples directly under the text field in your tool configuration

  4. Test your assistant after making any corrections

Additional Debugging

If the issue persists after checking your tool configurations:

  • Enable call recordings in the Technical section of your settings

  • Make a test call to reproduce the issue

  • Review the call recordings to identify where the conversation stops

This will help you pinpoint exactly which tool or configuration is causing the assistant to become unresponsive.
