Cannot authorize variable group in Azure Pipelines

I am constructing a multi-stage Azure Pipeline in Azure DevOps to build and release my product.

I want to use variable groups in this pipeline, so that I can substitute different configuration values for different deployment environments.

I am unable to authorize my variable groups to be used by the pipeline. When I manually run a build, I see a message on the summary page telling me the variable group is not authorized:

The Azure DevOps documentation says this is to be expected:

When you make changes to the YAML file and add additional resources (assuming that these not authorized for use in all pipelines as explained above), then the build fails with a resource authorization error that is similar to the following: Could not find a {RESOURCE} with name {NAME}. The {RESOURCE} does not exist or has not been authorized for use.

In this case, on the Summary page, you will see an option to authorize the resources on the failed build. If you are a member of the User role for the resource, you can select this option. Once the resources are authorized, you can start a new build.

I am a member of the User role for the variable group, and I am seeing the message, but I am presented with no option to authorize. Is there something else I need to do? Or is there another way I can authorize a specific pipeline to use a variable group?

Variable groups can only be accessed if they are imported at the "job" level.

Solution:

I have tested and tried to reproduce your issue. In order to solve it, you need to add the variable group under "job".

Explanation / Analysis:

This is how to reproduce and solve the issue:

First, I have tested with the below yaml script, by adding the variable group to the stage (literally at the same level as jobs):

stages:
- stage: build
  variables:
    - group: 789
  jobs:
  - job: run_build
    pool:
      vmImage: 'Ubuntu 16.04'
    steps:
    - script: echo Build

With this configuration, I was not able to use the variable group. I got the same issue as you:

I then moved the variable group into the job section of the yaml file:

stages:
- stage: build
  jobs:
  - job: run_build
    pool:
      vmImage: 'Ubuntu 16.04'
    steps:
    - script: echo Build
    variables:
    - group: 789

With the modified configuration, I was able to see and use the Authorize resources option in the error message:
