What happened?

When creating an Azure Load Balancer using Pulumi with Python, the backend pool is created but remains empty despite providing the necessary data.

We have attempted to populate the backend pool using LoadBalancerBackendAddressArgs, LoadBalancerBackendAddressArgs with a list of dictionaries, but none of these methods have worked.
If we create the load balancer in the first iteration and then hardcode the backend values in the next iteration, the backend data is populated correctly.

Pulumi completes the process successfully without any errors, but the backend pool remains empty.

Example

Our codebase is quite large, making it impractical to share the exact code. However, we have tested the plain example from the documentation and encountered the same behavior.

Output of pulumi about

python version 3.11.1
pulumi version 3.134.0

Additional context

We have been using the same code for the past few months without any issues. However, in the last 10 days, it has stopped working. We tried updating the Pulumi version, but the load balancer backend pool remains empty.
