Azure Service Bus Namespace creation is failing with unknown error

Question

When I am trying to create a Service Bus Namespace in Azure. It is failing with the below exception.

Microsoft.Azure.Management.ServiceBus.Models.ErrorResponseException: Operation returned an invalid status code 'NotFound'

Any help on why this error occurs and how to fix this?

Answer 1

Please check if the below steps help to work around:

I have faced similar kind of issue, but the status is Forbidden when creating the Service Bus topic request like Operation returned an invalid statu code: Forbidden

Resolve by adding role assignment to this service bus resource in the Azure Portal. Go to your service bus resource > Access Control (IAM) > Add Role assignment > Search your service principal name and add it as a role like owner, Save it.

In your case, I believe

Microsoft.Azure.Management.ServiceBus.Models.ErrorResponseException: Operation returned an invalid status code 'NotFound'

There are some causes regarding to similar error in Azure Service Bus Messaging Class like:

• The Operation you're trying to perform does not exist.
• Or the operation giving null in the request body.
• Entity trying to execute the operation against could not be found.
