Can't set broker properties on event grid

Question

Hi,
I've configured an event grid to send a message to a service bus topic.

I was expecting the properties to be mapped on the message properties of the Microsoft.Azure.ServiceBus.Message class/be able to see them on the Message Properties.

As we can see form the image above they are being mapped as custom properties instead of the regular message properties. Same happens when we receive the message on the code side, where we get the value as a user property instead of mapped on the message, so it's not a UI issue.

From the following links of the documentation I was expecting the message property to get populated:
-https://learn.microsoft.com/en-us/azure/event-grid/delivery-properties
-https://learn.microsoft.com/en-us/rest/api/servicebus/message-headers-and-properties#message-headers

Am I doing something wrong?
Appreciated,
Diogo Costa

Hi @Diogo Costa

I have got the update and only few properties (PartitionKey, SessionId and MessageId) are supported currently. I will be working with my team to update the Service Bus example section with the correct example and supported BrokeredMessage properties.

I have tested at my end and unfortunately Label is not supported currently. For supported properties (PartitionKey, SessionId and MessageId) you need to define these as HeaderName and the Value which you want to assign.

Note: Currently not all property are supported. We will update our document with more details.

Product group will add more fields as per the service bus documentation in the future but currently there is no ETA.

Below is the screenshot to add the MessageId of dynamic type (static is not supported.) For unsupported property/type you will get error message while saving it as below

Feel free to get back to me if you have any queries or concerns.
