bug(compute-availability-sets): Expand parameter does not work

[erezrokah]

Bug Report

• import path of package in question - github.com/Azure/azure-sdk-for-go/sdk/resourcemanager/compute/armcompute/v4

• SDK version - v4.1.0

• output of go version - go version go1.20.2 darwin/arm64

• What happened?

Trying to use the AvailabilitySetsClient NewListBySubscriptionPager with the expand parameter returns an error:

RESPONSE 400: 400 Bad Request
ERROR CODE: InvalidParameter
--------------------------------------------------------------------------------
{
  \"error\": {
    \"code\": \"InvalidParameter\",
    \"message\": \"The request URL is not valid.\",
    \"target\": \"$expand\"
  }
}
--------------------------------------------------------------------------------

• What did you expect or want to happen?

No error returned

• How can we reproduce it?

Use the code from https://github.com/Azure/azure-sdk-for-go/blob/cf448612bb22e9b72b05f9a52e226d04a0afc53b/sdk/resourcemanager/compute/armcompute/availabilitysets_client_example_test.go#L279 but with a real subscription.

I also tried with expand set to instanceView, instanceView\$ref, virtualMachines.

• instanceView because of https://learn.microsoft.com/en-us/rest/api/compute/availability-sets/list-by-subscription?tabs=Go#uri-parameters: also see https://pkg.go.dev/github.com/Azure/azure-sdk-for-go/sdk/resourcemanager/compute/armcompute/v4#AvailabilitySetsClientListBySubscriptionOptions and

• virtualMachines because of the code above and: https://learn.microsoft.com/en-us/rest/api/compute/availability-sets/list-by-subscription?tabs=Go#list-availability-sets-in-a-subscription.

• Anything we should know about your environment.

Nope

Maybe I holding it wrong? What is the correct value to pass for the expand parameter?

Hi 👋 When are we expected to receive an update on the issue?

[ianneal]

Any updates on this ticket?

[TravisCragg-MSFT]

I see 2 problems:

1. The sample for optional parameters is not correct and should be https://management.azure.com/subscriptions/{{subscriptionId}}/providers/Microsoft.Compute/availabilitySets?$expand=instanceView&api-version=2024-03-01
2. With the given and correct value, I receive the same error

I am following up to get clarity on how this is supposed to be done and update the documentation.

[TravisCragg-MSFT]

The valid parameter is listed as instanceView, but it should be "virtualMachines/$ref"

Below is a valid expand call.

https://management.azure.com/subscriptions/{{subscriptionId}}/providers/Microsoft.Compute/availabilitySets?$expand=virtualMachines/$ref&api-version=2024-03-01

We will be updating the doc to include the information.
