Hi Luke_UK95,
The issue you're encountering seems related to the ongoing problems with the GoHighLevel MCP connection. Many users have faced similar challenges, and it's been confirmed that the root of the problem is on the Vapi's end.
In your case, here are a few steps to try for further isolation of the problem:
1. **Test Individual Tools**: Go to your Vapi Dashboard, use the Test button in the tools section for each GoHighLevel tool with sample data, such as a known contact email or calendar ID. This can help identify if the problem lies in contact retrieval, calendar availability checking, or event creation.
2. **Check Configuration**: Ensure that the calendar IDs and API keys are correctly set and that all necessary permissions are granted in GoHighLevel. Double-check the input and format for timezone, start and end dates in the availability tool.
3. **Monitor Call Logs**: Review the call logs in the Vapi dashboard for specific error messages or issues related to the tool's calls.
Unfortunately, until the issue is resolved on Vapi's side, complete functionality might not be possible. Keep an eye on updates from the Vapi team regarding this issue.
