Exception when PlaceLimitOrder

[YLPeng]

I apologize if I did sth foolish, but I keep getting System.AggregateException: 'One or more errors occurred. (Object reference not set to an instance of an object.)' when I try to place limit order. (both TestPlaceOrder and real)
The inner exception stack trace is :
at Binance.Api.BinanceHttpClientExtensions.d__13.MoveNext()
--- End of stack trace from previous location where exception was thrown ---
at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw()
at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)
at Binance.Api.BinanceApi.d__34.MoveNext()

I am using version 0.2.0-alpha27, please help!

Thanks.

After trying a few things, I was able to place order when I downgrade the version to v0.2.0-alpha24.

Therefore, potentially, the issue was introduced since alpha 25.

@YLPeng, thanks for mentioning this. I see a potential problem that was introduced with 0.2.0-alpha25. If you are not using dependency injection (or IBinanceApiUserProvider) or creating an IApiRateLimiter when creating IBinanceApiUser the associated 'order' rate limiter is null. The changes with 0.2.0-alpha25 failed to check for that case.

So, assuming that's the case, just feed a new ApiRateLimiter() to new BinanceApiUser(rateLimiter: <the rate limiter>) and that should work.

@YLPeng, let me know if changes made to 0.2.0-alpha28 solves this issue. Thanks.
