Error in Attach folder to workspace step

[gxgrammatikos]

Hi,
When I run the pipeline, I'm getting the error below :
The problem seems to be at the Attach folder to workspace step.

• task: AzureCLI@2
  displayName: 'Attach folder to workspace'
  inputs:
  azureSubscription: $(ml-ws-connection)
  workingDirectory: $(ml-path)
  scriptLocation: inlineScript
  scriptType: 'bash'
  inlineScript: 'az ml folder attach -w $(ml-ws) -g $(ml-rg)'
