I am developing Terraform pipeline and i want to set a variable in a stage and then, output it so i can use it in another stage.

So this is my code that works:

stages:
- stage: Terraform_Plan
  displayName: Plan
  jobs:
  - job: Terraform_Plan
    displayName: Plan 

    steps:
    
    - powershell: |
        # made it shorter to get a point, that variable set here is not 
        # respected in next stage
        Write-Host "##vso[task.setvariable variable=anyTfChanges;isOutput=true]false"

      displayName: Detect any Terraform changes

And in another stage, i want to use it from condition:

 stage: Terraform_Apply
  displayName: Apply
  jobs:
  - deployment: Apply
    environment: dev
    displayName: Apply Terraform
    condition: and(succeeded(), or(eq(variables['Build.SourceBranch'], 'refs/heads/master'), eq('true', 'true'), eq(dependencies.Terraform_Plan.outputs['Terraform_Plan.anyTfChanges'], 'true')))

    strategy:
      runOnce:
        deploy:
          steps:

but it looks like that variable is not respected at all because Apply stage runs all the time, even when i set anyTfChanges variable to false

Any ideas how to make it works? I use windows agents
