"Microsoft.Xrm.RemotePlugin.Grpc.SandboxFabricGrpcClient.ExecutePluginInternal" Error - Troubleshooting

Recently I fumbled with this error in a Dynamics 365 CE Plugin:

System.ServiceModel.FaultException`1[Microsoft.Xrm.Sdk.OrganizationServiceFault]: Voila.

at Microsoft.Xrm.RemotePlugin.Grpc.SandboxFabricGrpcClient.ExecutePluginInternal(IRemotePluginRequest pluginRequest, ExecuteRequest executeRequest, Guid executionId, ISandboxFabricDuplexCommunicationHandler communicationHandler, Boolean returnTraceInfo, Guid organizationId, SandboxFabricCallTracker sandboxFabricCallTracker) +0x5d7

at Microsoft.Xrm.RemotePlugin.Grpc.SandboxFabricGrpcClient.ExecutePlugin(IRemotePluginRequest pluginRequest, IPluginExecutionContext executionContext, IPluginTracingService pluginTracingService, ISandboxFabricDuplexCommunicationHandler communicationHandler, ISet`1 earlySerializedPropertiesList, SandboxFabricCallTracker sandboxFabricCallTracker, ISandboxMemoryStreamProvider memoryStreamProvider) +0x2f0

at Microsoft.Xrm.RemotePlugin.Grpc.SandboxFabricCodeUnit.Execute(ILifetimeScope scope, IExecutionContext context, SandboxFabricCallTracker& sandboxFabricCallTracker, ISandboxMemoryStreamProvider memoryStreamProvider) +0x6e

at Castle.DynamicProxy.AbstractInvocation.Proceed() +0x2d

at Microsoft.Xrm.RemotePlugin.Client.Interceptors.SandboxFabricPluginTraceInterceptor.Intercept(IInvocation invocation, IExecutionContext context, SandboxFabricCallTracker sandboxFabricCallTracker) +0x1f

While investigating, the exception is unhandled and caught at FaultException:

catch (FaultException<OrganizationServiceFault> ex)

{

    throw new InvalidPluginExecutionException("Voila.", ex);

}

The rootcause - I was assigning a date only field while creating an entity record using System.DateTime.Now.ToShortDateString(), it's fixed when I changed to System.DateTime.Today

So basically the platform throwing this error without more useful context or inner exception, due to the time component missing in datetime field. Sigh!

Happy learning :)
