question

Hi, i'm trying to execute an Azure CloudScript function through a Scheduled Task but it keeps failing. I need to get and set a value on Internal Title Data. Here's the code and error.

[FunctionName("TaskTest")]
public static async Task Run([HttpTrigger(AuthorizationLevel.Function, "post", Route = null)] HttpRequest req, ILogger log)
{
    string body = await req.ReadAsStringAsync();
    ScheduledTaskFunctionExecutionContext<object> ctx = JsonConvert.DeserializeObject<ScheduledTaskFunctionExecutionContext<object>>(body);

    if (ctx.TitleAuthenticationContext != null)
    {
        SetTitleDataRequest request = new SetTitleDataRequest
        {
            Key = "Test",
            Value = "1",
            TitleId = ctx.TitleAuthenticationContext.Id
        };
        await PlayFabAdminAPI.SetTitleInternalDataAsync(request);
    }
}
