Thank you for your feedback. Tagging and routing to the team member best able to assist.
Hi @ivandamyanov. Thanks for reaching out and we regret that you're experiencing difficulties. Service Bus does not inspect nor alter the bytes passed to it for the body. If you're not seeing the body populated when using BinaryData but are when using Newtonsoft, it seems likely there's something in your structure that System.Text.Json handles differently than Newtonsoft.
Unfortunately, there's not enough context to speculate further. Can you share a small, stand-alone sample that reproduces the behavior that you're asking about?
Hi @ivandamyanov. Thank you for opening this issue and giving us the opportunity to assist. To help our team better understand your issue and the details of your scenario please provide a response to the question asked above or the information requested above. This will help us more accurately address your issue.
Library name and version
Azure.Messaging.ServiceBus 7.18.1
Describe the bug
I have a type called MyRequest with a public property TransactionId. I'm trying to create a ServiceBusMessage instance in the following way:
var message = new ServiceBusMessage(BinaryData.FromObjectAsJson(MyRequest)) { MessageId = messageId, Subject = "mySubject", };
After inspecting the message.Body property - it is empty even though TransactionId is already a valid Guid in theMyRequest
instance passed toFromObjectAsJson
.As a workaround, I used Newtonsoft JsonConvert and UTF8.GetBytes like this and it works fine - the body is not empty:
var serializedMessageBody = Newtonsoft.Json.JsonConvert.SerializeObject(MyRequest); var bytes = Encoding.UTF8.GetBytes(serializedMessageBody); return new ServiceBusMessage(new BinaryData(bytes)) { MessageId = messageId, Subject = messageLabel };
Any idea what is the issue with BinaryData not filling in the Body property properly depending on the serializer? By the way, this seems to depend on the class being serialized because in another piece of code I have with
AnotherRequest
, FromObjectAsJson is used and then the Body is filled correctly.Expected behavior
The Body should be filled in both cases
Actual behavior
The Body of ServiceBusMessage is empty
Reproduction Steps
I think using classes like the ones explained below will allow a reproduction of the issue:
The different between this piece of code with
AnotherRequest
and the one above withMyRequest
is that:AnotherRequest
has these attributes (and it works with FromObjectAsJson):[System.CodeDom.Compiler.GeneratedCodeAttribute("Microsoft.Tools.ServiceModel.Svcutil", "2.1.0")] [System.Diagnostics.DebuggerStepThroughAttribute()] [System.Xml.Serialization.XmlTypeAttribute(Namespace = "http://example.namespace")]
and the public properties have:
[System.Xml.Serialization.XmlElementAttribute(Form = System.Xml.Schema.XmlSchemaForm.Unqualified, Order = 0)]
while the
MyRequest
class has these[System.Diagnostics.DebuggerStepThroughAttribute()] [System.CodeDom.Compiler.GeneratedCodeAttribute("Microsoft.Tools.ServiceModel.Svcutil", "2.1.0")] [System.ComponentModel.EditorBrowsableAttribute(System.ComponentModel.EditorBrowsableState.Advanced)] [System.ServiceModel.MessageContractAttribute(WrapperName="OnConfirmationRequest", WrapperNamespace="http://example.namespace", IsWrapped=true)]
and the properties:[System.ServiceModel.MessageBodyMemberAttribute(Namespace="http://SecureApp/2017/SecureAppResponse", Order=0)]
Environment
Hosting in a ServiceFabric cluster on a Windows OS. The code is in a .NET 6 project.
