[BUG] Unknown MonitorConditionOperator value. (Parameter 'value') Actual value was Equal.

[geolawton]

Library name and version

Azure.ResourceManager.Monitor 1.3.0

Describe the bug

It's possible for alert rules to have the Operator of "Equal" when created in the Azure Portal. The enum MointorConditionOperator Does not have a value for this to map to and will crash when it attempts to do so.

Expected behavior

Should be able to query for alerts that have a "Equal to" operator

Actual behavior

Will crash with an ArgumentOutOfRangeException when attempting to get an alert rule that has "table rows = 0"

Reproduction Steps

Create a log search alert rule using Application Insights.

• Set the Alert Logic condition to be as such:
  
• Confirm that the operator is set to Equal on "Review + Create"
  
• Run the following code to get all alert rules. It will crash on GetAllAsync() when trying to get the alert with the Equal operator

var client = new ArmClient(new DefaultAzureCredential());
var subscription = client.GetDefaultSubscription();
var allRgs = subscription.GetResourceGroups();

var scheduledQueryRules = new List<ScheduledQueryRuleResource>();
foreach(var rg in allRgs)
{
     await foreach(var scheduledQueryRule in rg.GetScheduledQueryRules().GetAllAsync())
     {
         currentScheduledQueryRule = scheduledQueryRule;
         scheduledQueryRules.Add(scheduledQueryRule);
     }
}

There is a workaround where changing the alert in the Azure Portal to use GreaterThen and LessThan will circumnavigate the issue. E.g. table rows = 0 becomes table rows < 1

This is a service issue. The defined value is: Equals, but the actual response is Equal.

We had a quick fix on the SDK, waiting for review & merge.
