I have created a yaml script to build pipelines for Azure Data Factory with Azure DevOps.

During the Powershell Script job the pipeline fails with the error:

##[error]PowerShell exited with code ‘1’.

The full error is as follows:

The yaml script is a follows:

# Starter pipeline
# Start with a minimal pipeline that you can customize to build and deploy your code.
# Add steps that build, run tests, deploy, and more:
# https://aka.ms/yaml

trigger:
- adf_publish

pool:
  vmImage: ubuntu-latest

steps:
- script: |
    tree $(System.DefaultWorkingDirectory)
  displayName: Show file structure of System.DefaultWorkingDirectory during a build


- task: AzurePowerShell@5
  inputs:
    azureSubscription: 'NewConnectionName'
    ScriptType: 'FilePath'
    ScriptPath: '$(System.DefaultWorkingDirectory)/caplogic-warehouse-dev-df/PrePostDeploymentScript.ps1'
- task: AzurePowerShell@5
  inputs:
    azureSubscription: 'NewConnectionName'
    ScriptType: 'FilePath'
    ScriptPath: '$(System.DefaultWorkingDirectory)/caplogic-warehouse-dev-df/PrePostDeploymentScript.ps1'
    ScriptArguments: '-armTemplate "$(System.DefaultWorkingDirectory)/caplogic-warehouse-dev-df/ARMTemplateForFactory.json" -ResourceGroupName $(ResourceGroup) -DataFactoryName $(DataFactory) -predeployment $true -deleteDeployment $false'
    azurePowerShellVersion: 'LatestVersion'

Can someone let me know what could cause the Powershell script to fail with code ‘1’?
