Microsoft Dev Ops yaml variables between deployments - azure

Question

So at it's core what I'm essentially trying to do is this:
https://learn.microsoft.com/en-us/azure/devops/pipelines/process/deployment-jobs?view=azure-devops&preserve-view=true#support-for-output-variables
Which breaks down to the fact that I have a single deployment template that produces an output variable that I want to map back to a variable in my main template so that I can use it in subsequent deployment templates.
I have created a github project with all of my yaml templates here
https://github.com/MCKRUZ/azure-pipelines
but the crux of the problem lies in these few lines. First I'm calling a template deployment in my main "development.yaml" file.
# Deploy
# ------
- stage: Deploy
displayName: Deploy - Development
jobs:
- template: jobs/jobs-deploy-spa-arm-template.yaml
parameters:
environment: '$(environment)'
serviceConnection: '$(serviceConnection)'
subscriptionId: '$(subscriptionId)'
resourceGroup: '$(resourceGroup)'
storageAccountName: '$(storageAccountName)'
cdnEndpointName: '$(cdnEndpointName)'
cdnProfileName: '$(cdnProfileName)'
deploymentLocation: '$(deploymentLocation)'
armTemplateArtifactName: ${{ variables['armTemplateArtifactName'] }}
storageAccountCSMFilePath: '$(storageAccountCSMFilePath)'
storageAccountCSMParametersFile: '$(storageAccountCSMParametersFile)'
deployCDN: '${{ variables.isProduction }}'
cdnCSMFilePath: '$(cdnCSMFilePath)'
cdnCSMParametersFile: '$(cdnCSMParametersFile)'
That template looks like this:
# Parameters

Where I'm using these two lines
- script: echo "##vso[task.setvariable variable=myOutputVar;isOutput=true]this is the deployment variable value"
name: setvarStep
- script: echo $(setvarStep.myOutputVar)
name: echovar
To try and isolate a way that I can create a variable that will be able to be used back in my main yaml file. When I look at the logs, the second echo successfully echos out the variable so I know that part works at least. Once this runs, back in my main yaml file I call this.
- job: job_deploy_code
displayName: Deploy Some Code
dependsOn: armTemplates
variables:
myVarFromDeploymentJob: $[ dependencies.armTemplates.outputs['deploy_Development.setvarStep.myOutputVar'] ]
steps:
- script: "echo $(myVarFromDeploymentJob)"
name: echovar
Which is just supposed to echo back what is in my variable. Right now it's blank. I know it's some stupid syntax that I'm not seeing but I can't for the life of me figure out what it is.

Answer 1

I solved this with the correct syntax
- job: job_deploy_code
displayName: Deploy Some Code
dependsOn: armTemplates
variables:
myVarFromDeploymentJob: $[ dependencies.armTemplates.outputs['armTemplates.setvarStep.myOutputVar'] ]
