Same error.
I added a breakpoint on PSGraph.psm1 script line 904 to get the value of $standardInput.ToString() and attached to the thread.
standardinput.txt

Thx in advance

I had this same issue when trying to run this on a self-hosted build agent. I was able to fix this by modifying the installed
C:\Program Files\WindowsPowerShell\Modules\AzViz\1.2.1\src\public\Export-AzViz.ps1 file. I didn't have any problems running Export-AzViz from Powershell locally, but when I tried to run it in an Azure DevOps pipeline, it would fail on this line. I reformatted the line and learned a bit about here strings..

I added a $combined variable to catch the concatenation.. In the end, its just trying to add "strict" to the graph output before passing it to Export. This resolved the issue running from my build machine.

yaml steps to generate diagrams from an Azure Devops pipeline:
I pre-installed Az-Viz, etc on the build agent, then put this in the pipeline.
create a variable called "resource_groups" and put a list of the resource groups you want to model. output.png will get attached to the pipeline as an artifact.
`
steps:

• task: AzurePowerShell@5
  inputs:
  azureSubscription: 'MySubscription'
  ScriptType: 'InlineScript'
  Inline: 'Import-Module AzViz'
  preferredAzurePowerShellVersion: '3.1.0'

• task: AzurePowerShell@5
  inputs:
  azureSubscription: 'MySubscription'
  ScriptType: 'InlineScript'
  workingDirectory: $(Build.SourcesDirectory)
  Inline: "Export-AzViz -ResourceGroup $(resource_groups) -Theme light -OutputFormat png -LabelVerbosity 2 -Direction top-to-bottom -OutputFilePath $(Build.ArtifactStagingDirectory)/output.png"
  preferredAzurePowerShellVersion: '3.1.0'

• task: CopyFiles@2
  inputs:
  SourceFolder: 'C:\Windows\ServiceProfiles\NetworkService\AppData\Local\Temp'
  Contents: 'output.png'
  TargetFolder: '$(Build.ArtifactStagingDirectory)'

• task: PublishBuildArtifacts@1
  inputs:
  PathtoPublish: '$(Build.ArtifactStagingDirectory)'
  ArtifactName: 'drop'
  publishLocation: 'Container'`

it seems a few people get this @gstevens-kyriba would you mind submitting a PR with your fix in it so all could benefit?
