set and refer to variables in yaml - azure-devops

Question

I have the following yml code that sets and refers to some variables as follows:
<one.yml>
- task: AzurePowerShell#4
displayName: 'Copy functions templates'
inputs:
azureSubscription: ${{parameters.serviceConnection}}
ScriptPath: ${{ parameters.root }}/Scripts/ReleaseManagement/CopyChildTemplatesToContainer.ps1
ScriptArguments: '-resourceGroupName ''${{ parameters.solutionAbbreviation}}-data-${{ parameters.environmentAbbreviation}}''
name: copyFunctionsTemplates
- powershell: |
Write-Host "##vso[task.setvariable variable=data_containerSASToken;isOutput=true]$(copyFunctionsTemplates.containerSASToken)"
Write-Host "##vso[task.setvariable variable=data_containerEndPoint;isOutput=true]$(copyFunctionsTemplates.containerEndPoint)"
displayName: 'set data output variables'
name: dataVariables
<two.yml>
stages:
- deployment: ${{ parameters.stageName }}_DeployResources
displayName: ${{ parameters.stageName }}_DeployResources
- stage: ${{ parameters.stageName }}
dependsOn: ${{ parameters.dependsOn }}
condition: ${{ parameters.condition }}
jobs:
- deployment: ${{ parameters.stageName }}_DeployResources
displayName: ${{ parameters.stageName }}_DeployResources
steps:
- template: one.yml
jobs:
- job: ${{ parameters.stageName }}_DeployFunctions
dependsOn: ${{ parameters.stageName }}_DeployResources
variables:
data_containerEndPoint: $[ dependencies.DeployResources.outputs['DeployResources.dataVariables.data_containerEndPoint'] ]
data_containerSASToken: $[ dependencies.DeployResources.outputs['DeployResources.dataVariables.data_containerSASToken'] ]
steps:
- ${{ each func in parameters.functionApps }}:
- template: three.yml
<three.yml>
steps:
- task: AzureResourceGroupDeployment#2
displayName: 'deploy ${{ parameters.name }} data resources'
inputs:
azureSubscription: ${{parameters.serviceConnection}}
resourceGroupName: ${{parameters.solutionAbbreviation}}-data-${{parameters.environmentAbbreviation}}
location: ${{parameters.location}}
csmFile: ${{ parameters.root }}/functions_arm_templates/${{ parameters.name }}/Infrastructure/data/template.json
csmParametersFile: ${{ parameters.root }}/functions_arm_templates/${{ parameters.name }}/Infrastructure/data/parameters/parameters.${{parameters.environmentAbbreviation}}.json
overrideParameters: -environmentAbbreviation "${{parameters.environmentAbbreviation}}"
-tenantId "${{parameters.tenantId}}"
-solutionAbbreviation "${{parameters.solutionAbbreviation}}"
-containerBaseUrl "$(data_containerEndPoint)functions/${{ parameters.name }}/Infrastructure/data/"
-containerSasToken "$(data_containerSASToken)"
deploymentMode: 'Incremental'
On enabling the debug mode while running pipeline, I see values printed for data_containerSASToken and data_containerEndPoint from the task 'Copy functions templates' however I see empty values from the task 'deploy data resources'. What am I missing?

Your problem may be in when you retrieve the output from the previous job:
data_containerEndPoint: $[ dependencies.DeployResources.outputs['DeployResources.dataVariables.data_containerEndPoint'] ]
That's looking for a prior job called DeployResources, but the prior job is actually called {{ parameters.stageName }}_DeployResources.
