I'm trying to connect to Azure Open AI Instance, I'm pathing APIKey, BaseURL and DefaultModel variables and getting Resource not found. ``` const g = new GPTScript({ APIKey: "<key>", BaseURL: "https://azureinstance.openai.azure.com", DefaultModel: "gpt-4o", }); ``` error: [cause]: 'error, status code: 404, message: Resource not found'
