Use variable from AWSCLI in azure pipelines for script - azure-devops

Question

I have a build process where I need to use a token, received through the AWSCLI. So far I have connected aws to my azure pipelines but I am having trouble setting up my yaml.
I want to fetch the relevant token to use it later as a variable in my script.
As you can see in my yaml I am running a powershell script with codeartifact and I am saving the value to my myOutputVar. The powershell script does not throw an error.
However, later when I run the building script that variable is not present resulting in ECHO is off.
How can I ensure the value received in the task can be used later in the script/build part?
trigger:
- azure-pipelines
pool:
vmImage: windows-latest
steps:
- task: NodeTool#0
inputs:
versionSpec: '10.x'
displayName: 'Install Node.js'
- task: AWSPowerShellModuleScript#1
inputs:
awsCredentials: 'AWS Connection'
regionName: 'eu-central-1'
scriptType: 'inline'
inlineScript: '##vso[task.setvariable variable=myOutputVar;]aws codeartifact get-authorization-token --domain somedomain --domain-owner 444.... --query authorizationToken --output text; '
- script: |
echo %myOutputVar%
npm ci
npm run build
displayName: 'npm install and build'

Your inline script can be multiple lines, and since this is PowerShell you can do something like:
inlineScript: |
$authToken = aws codeartifact get-authorization-token `
--domain somedomain `
--domain-owner 444.... `
--query authorizationToken `
--output text
Write-Host "##vso[task.setvariable variable=myOutputVar;]$authToken"
