In the code below, I have a variable (storage_account_name) being output in the first job, within the task called TaskName. I want to be able to retrieve its value in a second job (deployment job), but the variable is empty.

jobs:
- job: dependency
  steps:
  - template: my_template.yml

- deployment: my_deployment
  environment: MyEnvironment
  dependsOn: 
  - dependency
  variables:
  - name: storage_account_name
    value: $[ dependencies.dependency.outputs['TaskName.storage_account_name'] ]
  strategy:
    runOnce:
      deploy:
        steps:
        - checkout: self
        - template: another_template.yml
          parameters: 
            TF_VAR_storage_account_name: $(storage_account_name)

The exact same code works well when the second job is a normal job. Any idea what I am doing wrong?
