Parameterize azureSubscription from variable group in yaml pipeline

I'm using Yaml for Azure devops pipeline. I am using a hierarchical style for that.

I'm having one top level yaml: feature.yaml which has following structure:

trigger:
...
pool:
  vmImage: ...
  
variables:
  group: ...

stages:
  - template: deploy.yaml
    parameters:
      subName: $(subscription) #This should be taken from Variable group

I have deploy.yaml as:

stages:
    - stage: deploy
      jobs:
        - job: deploy
          steps:
          - task: AzureKeyVault@1
            inputs:
              azureSubscription: $(paramaters.subName) #This should be resolved from parameter passed form feature.yaml
              KeyVaultName: ...
              SecretsFilter: '*'
              RunAsPreJob: true

However, whenever I run this from Azure DevOps, I'm getting this error:

There was a resource authorization issue: "The pipeline is not valid. Job deploy: Step AzureKeyVault input ConnectedServiceName references service connection $(paramaters.subName) which could not be found. The service connection does not exist or has not been authorized for use. For authorization details, refer to https://aka.ms/yamlauthz."

It seems pipeline is not able to resolve value of azureSubscription name from variable group.

Any suggestions?

I discovered that when the YAML is initially parsed it expects the variable group to be in scope. I needed to move my variable group to the top of the YAML file and then it found the azure subscription variable. Not what I was expecting.

for those who are looking for resolution,

Here's what you'll need to do: In the Top-level feature.yaml, Add the desired variable group name and pass in the parameter from the template which has the azure subscription name:

variables:
  - group: xxx

  - template: deploy.yaml
    parameters:
      subName: $(_subscriptionName)

And utilize that parameter in template deploy.yaml:

- task: AzureKeyVault@1
  inputs:
     azureSubscription: ${{ parameters.subName}}
     keyVaultName: xxx
     secretsFilter: '*'

Its a known issue currently that we can not use variable from variable group directly to azureSubscription input of AzureKeyVault task as per this thread.

Thi work around should work fine!

We had a similar issue to this and it was because we missed off the - in the yaml under variables:

variables:
  group: ...

To:

variables:
  - group: ...

This fixed the issue for us.
