So not the toolID from my Vapi Dashboard - is the rest setup ok? As the assistant is calling the function but keeps saying they cannot schedule the call "tools": [ { "type": "function", "messages": [ { "type": "request-start", "content": "Let me check the available times. Please wait..." }, { "type": "request-complete", "content": "Your callback has been scheduled." }, { "type": "request-failed", "content": "I couldn't schedule the callback right now. Please try again later." }, { "type": "request-response-delayed", "content": "It appears there is some delay in scheduling the callback.", "timingMilliseconds": 2000 } ], "function": { "name": "getCallbackDateTime", "parameters": { "type": "object", "properties": { "datetime": { "type": "string", "description": "The date and time the user wants the callback in ISO format." } }, "required": ["datetime"] }, "description": "This function captures the date and time the user would like a callback during a call. It validates the input, saves the information in the database, and schedules the callback. If successful, it returns a confirmation message to the user." }, "async": false, "server": { "url": "https://" } } ],
