Description
When using 2020-05-01 network API, when I want to remove a load balancer rule that the load balancer is attached to VMSS, the request will fail.
The complete flow is as below:

Contributor guide
Research direction
The payload identifies the 2020-05-01 Network API and includes GET and PUT load balancer examples, but names no repository file, test, or entry point. Start by locating the specification for that API version and compare its load balancer rule model with the failing request. Done means the remove/update behavior is resolved and verified by the relevant specification tests.
