ASP.Net OData-现有连接被远程主机强行关闭

Question

我有一个非常基本的OData Web服务，它会在异常发生后不时抛出。

Startup.cs

services.AddOData();

Controller.cs：

    [EnableQuery]
    public async Task<IQueryable<T>> Get()
    {
        // execute the inital request to get the 'root'
        var list = ((IEnumerable<T>) _rabbitService.GetFromQueue(typeof(T), typeof(IEnumerable<T>)));

        return new EnumerableQuery<T>(list);
    }

即使将异步Get更改为sync方法，它也会引发此异常。

一切正常，除了我在Kestrel日志中得到的例外。即使有这个例外，每个请求看起来也都正确回答了。为此，我编写了一个脚本，该脚本在得到答案后立即调用端点。即使有例外情况，HTTP返回码也为200。

这是什么问题？
