TrafficManagerEndpoint cmdlets: getting Bad Request (400) and NullReferenceExceptions

I'm attempting to enable/disable Traffic Manager endpoints via Powershell to help with environment configuration. On one of our Resource Groups the cmdlets worked fine, but we're seeing some strange behavior in others.

In one case, passing in a TrafficManagerEndpoint directly to a cmdlet (via pipeline or parameter) returns a 400 and vomits the full HTML:

> $tm = Get-AzureRmTrafficManagerProfile -Name <tm-name> -ResourceGroupname <rg-name>
> $tm.Endpoints[0] | Disable-AzureRmTrafficManagerEndpoint

Confirm
Are you sure you want to disable endpoint '<tm-endpoint-name>' of Profile '<tm-name>'?

The same happens when using Enable-AzureRmTrafficManagerEndpoint and Set-AzureRmTrafficManagerEndpoint.

When invoking the cmdlet using resource names, Diable-AzureRmTrafficManagerEndpoint works just fine, but when invoking Enable-AzureRmTrafficManagerEndpoint this way I get a NullReferenceException:

> Disable-AzureRmTrafficManagerEndpoint -Name <tm-endpoint-name> -ProfileName <tm-name> -ResourceGroupName <rg-name> -Type AzureEndpoints

I'm certain the names are correct. Any insight into this? It seems like my AzureRM.TrafficManager module is out of sync with Azure, but I've tried installing whatever's available in the Web Platform Installer and haven't gotten anywhere. (Module version is 3.0.0). Thanks!

EDIT: Some more info that I forgot:

.NET Azure SDK version: 2.9

Powershell version:

According to your description, we can use Azure PowerShell script like this to enable or disable traffic manager endpoints.

Use this script to disable Azure traffic manager endpoints:

PS C:\Users> $endpoint1 = Get-AzureRmTrafficManagerEndpoint -Name web1 -Type AzureEndpoints -ProfileName jasontm -ResourceGroupName jason
PS C:\Users> $endpoint1.EndpointStatus
Enabled
PS C:\Users> $endpoint1.EndpointStatus = "Disabled"
PS C:\Users> $endpoint1.EndpointStatus
Disabled
PS C:\Users> $endpoint1 | Set-AzureRmTrafficManagerEndpoint


Id                    : /subscriptions/5384xxxx-xxxx-xxxx-xxxx-xxxxe29axxxx/resourceGroups/jason/providers/Microsoft.Network/trafficManagerProfiles/jasontm/azureEndpoints/web1
Name                  : web1
ProfileName           : jasontm
ResourceGroupName     : jason
Type                  : AzureEndpoints
TargetResourceId      : /subscriptions/5384xxxx-xxxx-xxx-xxxx-xxxxe29axxxx/resourceGroups/jason/providers/Microsoft.Network/publicIPAddresses/jasonweb1-ip
Target                : jasonweb1.eastus.cloudapp.azure.com
EndpointStatus        : Disabled
Weight                : 1
Priority              : 1
Location              : East US
EndpointMonitorStatus : Disabled
MinChildEndpoints     :

Use this script to enable Azure traffic manager endpoints:

PS C:\Users> $endpoint1 = Get-AzureRmTrafficManagerEndpoint -Name web1 -Type AzureEndpoints -ProfileName jasontm -ResourceGroupName jason
PS C:\Users> $endpoint1.EndpointStatus
Disabled
PS C:\Users> $endpoint1.EndpointStatus = "Enabled"
PS C:\Users> $endpoint1.EndpointStatus
Enabled
PS C:\Users> $endpoint1 | Set-AzureRmTrafficManagerEndpoint


Id                    : /subscriptions/5384xxxx-xxxx-xxxx-xxxx-xxxxe29axxxx/resourceGroups/jason/providers/Microsoft.Network/trafficManagerProfiles/jasontm/azureEndpoints/web1
Name                  : web1
ProfileName           : jasontm
ResourceGroupName     : jason
Type                  : AzureEndpoints
TargetResourceId      : /subscriptions/5384xxxx-xxxx-xxxx-xxxx-xxxxe29axxxx/resourceGroups/jason/providers/Microsoft.Network/publicIPAddresses/jasonweb1-ip
Target                : jasonweb1.eastus.cloudapp.azure.com
EndpointStatus        : Enabled
Weight                : 1
Priority              : 1
Location              : East US
EndpointMonitorStatus : CheckingEndpoint
MinChildEndpoints     :

By the way, I am use Azure PowerShell version 3.7.0:

PS C:\Users> Get-Module -ListAvailable -Name Azure -Refresh


    Directory: C:\Program Files (x86)\Microsoft SDKs\Azure\PowerShell\ServiceManagement


ModuleType Version    Name                                ExportedCommands
---------- -------    ----                                ----------------
Manifest   3.7.0      Azure                               {Get-AzureAutomationCertificate, Get-AzureAutomationConnection, New-AzureAutomationConnection, Remove-AzureAutomationConnection...}
