I have been using and testing our assistant with public keys for the last 2 weeks with no problems. Today I added some custom assistant properties

vapiInstance = window.vapiSDK.run({
                    apiKey: apiKey,
                    assistant: assistantID,
                    config: buttonConfig,
                    assistantOverrides: {
                        name: 'Custom Assistant Name', // works
                        variableValues: {
                            "name": "John",
                        }
                });

It worked with assistantOverrides -> name But when I added assistantOverrides -> variableValues then it started the CORS errors. When I remove the code for assistantOverrides I still get the CORS errors. I am not sure how it could be related, but that is what I changed on my end. I have tried creating a new assistant and a new public-key with no access options and tried making one with my AWS Lambda function as the allowed access. Neither work any more, I get the above error Please help, this is quite urgent Chris
