SaveChangesAsync not working inside Azure webjob - azure

Question

I have an Azure job which asynchronously saves records to the database. I am finding that it does not actually save anything to the database. I am definitely using async/awaits everywhere. I am adding parent (market) and child records. My database has referential constraints so the parent has to exist before the child, but that should be fine as I am doing them in the right order. I have no try-catches around my methods and there is nothing in the azure logs so it appears the job is succeeding. I have called Method1 with an await from a Winforms exe and it works fine from that. What can be wrong?
public static async Task MyJob([TimerTrigger("00:02:00", RunOnStartup = true)] TimerInfo timerInfo, TextWriter log)
{
await Jobs.Method1(Client, Logger);
}
public static async Task Method1(IClient client, ILogger logger)
{
await DataRepository.AddMarket(event.Id, event.MarketId);
await DataRepository.AddMarketChild(event.MarketId, 999);
}
public static async Task<Market> AddMarket(string eventId, string marketId)
{
using (var ctx = BTBEntities.CreateContext())
{
var market = new Market()
{
MarketId = marketId,
EventId = eventId,
};
ctx.Markets.Add(market);
await ctx.SaveChangesAsync();
return market;
}
}
public static async Task<HorseBet> AddHorseBet(string marketId, long selectionId)
{
using (var ctx = BTBEntities.CreateContext())
{
var bet = new MarketChild()
{
MarketId = marketId,
SelectionId = selectionId,
};
ctx.MarketChilds.Add(bet);
await ctx.SaveChangesAsync();
return bet;
}
}

Turns out there was a database problem it was just being swallowed by Azure. This is how I fixed it.
public override System.Threading.Tasks.Task<int> SaveChangesAsync()
{
try
{
return base.SaveChangesAsync();
}
catch (DbEntityValidationException ex)
{
var errorMessages = ex.EntityValidationErrors
.SelectMany(x => x.ValidationErrors)
.Select(x => x.ErrorMessage);
var fullErrorMessage = string.Join("; ", errorMessages);
var exceptionMessage = string.Concat(ex.Message, " The validation errors are: ", fullErrorMessage);
throw new DbEntityValidationException(exceptionMessage, ex.EntityValidationErrors);
}
}
