Hey @Gravity My recommendation on this is: For the dashboard page you are having problems with, open Chrome/Edge Developer Tools (All browsers have an equivalent if you use a different Browser, except on phones). Go to the network tab where you can see the http requests sent and the response from the server. Press the Save button (or what ever functionality you are having errors for). Find the network message that appeared when you press the save button that is highlighted in Red, and returned an error. Look in the response body. VAPI server is pretty good about returning correct errors. The dashboard just stinks and often times does not display the detailed backend error, instead displaying a generic error like: "Save Failed" or something else useless. I have figured out at least a half dozen VAPI Dashboard issues this way. Everything from why the Tool --> "Duplicate" tool button fails to why the "Get Free Phone Number" was failing for the VAPI recommended area codes.
