I want to execute the flow fetchXml by webapi,
<fetch version='1.0' output-format='xml-platform' mapping='logical' aggregate='true'>
<entity name = 'new_mob_notification' >
<attribute name='new_name' alias='colcount' aggregate='countcolumn'/>
<filter type ='and'>
<condition attribute = 'new_readstatus' operator= 'eq' value = '1' />
<condition attribute = 'statecode' operator= 'eq' value = '0' />
<condition attribute = 'new_receiver' operator= 'eq' value = '67781f72-450c-e611-80bc-000c292d3ec1' />
</filter>
</entity>
</fetch>
when executed by HTTP GET with QueryString , it run successfully.
but when I run in $batch , crm throw the follow exception:
{"Message":"'select' and 'expand' cannot be both null or empty.","ExceptionMessage":"'select' and 'expand' cannot be both null or empty.","ExceptionType":"System.ArgumentException","StackTrace":" 在 System.Web.OData.Query.SelectExpandQueryOption..ctor(String select, String expand, ODataQueryContext context, ODataQueryOptionParser queryOptionParser)\r\n 在 Microsoft.Crm.Extensibility.OData.CrmODataEntityTypeSerializer.CreateSelectExpandNode(EntityInstanceContext entityInstanceContext)\r\n 在 System.Web.OData.Formatter.Serialization.ODataEntityTypeSerializer.WriteEntry(Object graph, ODataWriter writer, ODataSerializerContext writeContext, IEdmTypeReference expectedType)\r\n 在 System.Web.OData.Formatter.Serialization.ODataFeedSerializer.WriteFeed(IEnumerable enumerable, IEdmTypeReference feedType, ODataWriter writer, ODataSerializerContext writeContext)\r\n 在 System.Web.OData.Formatter.ODataMediaTypeFormatter.WriteToStream(Type type, Object value, Stream writeStream, HttpContent content, HttpContentHeaders contentHeaders)\r\n 在 System.Web.OData.Formatter.ODataMediaTypeFormatter.WriteToStreamAsync(Type type, Object value, Stream writeStream, HttpContent content, TransportContext transportContext, CancellationToken cancellationToken)\r\n--- 引发异常的上一位置中堆栈跟踪的末尾 ---\r\n 在 System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task)\r\n 在 System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)\r\n 在 System.Web.OData.Batch.ODataBatchResponseItem.<WriteMessageAsync>d__0.MoveNext()\r\n--- 引发异常的上一位置中堆栈跟踪的末尾 ---\r\n 在 System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task)\r\n 在 System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)\r\n 在 System.Web.OData.Batch.ODataBatchContent.<SerializeToStreamAsync>d__0.MoveNext()\r\n--- 引发异常的上一位置中堆栈跟踪的末尾 ---\r\n 在 System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task)\r\n 在 System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)\r\n 在 System.Web.Http.WebHost.HttpControllerHandler.<WriteBufferedResponseContentAsync>d__1b.MoveNext()","ErrorCode":500}
