webapp:Unable to create serviceplan using the CLI (System.Collections.Generic.HashSet`1[System.String])

[liron-navon]

version 2.0.62

Describe the bug
I'm trying to create an appservice plan using azure cli from the pipeline (azure devops => pipelines => releases => Azure CLI block => inline script), but it doesn't work and throws a very cryptic error message (see "additional context").

Also apparently sku is required, even though the documentation says it's optional.

To Reproduce
You can replace the sku here with different types like B1 or "S1" - but none work.
I also tried with different configurations, but it doesn't work with any.

az appservice plan create -g MyResourceGroup -n MyPlan --number-of-workers 4 --sku S1 --is-linux

As seen in the documentation

Expected behavior
A service plan should be created

Environment summary
Azure pipeline

Additional context

2019-06-25T11:51:51.4165536Z ERROR: This version of AppServiceEnvironments only supports System.Collections.Generic.HashSet`1[System.String] Sku(s).

@panchagnula assigned this to you for current sprint, can you take a look?

This may not be applicable here, but wanted to share just in case. I am using terraform to deploy app service plans into app service environments using Terraform and the AzureRM provider. Just now I was getting almost exactly the same error message (googling brought me to this issue). It turns out that the app service plan sku that I was attempting to deploy is not supported in the ASEV2 I deployed. ASEV2 uses isolated tier, ASEV1 uses premium tier.

@TechnologyAnimal I am glad you figured out what was causing the failure here. Did running the command with --debug show a useful error message?

@liron-navon looks like you are trying to use this in a ASE , mostly likely ASE V2?
ASEs don't support B1, standard or shared SKU see documentation here https://docs.microsoft.com/en-us/azure/app-service/environment/app-service-app-service-environment-intro
