I have a pipeline task which is as follow:

- task: [email protected]
displayName: 'Script1'      
inputs:
  filePath: '$(System.DefaultWorkingDirectory)/Terraform/helloworld1.ps1'

And it run a helloworld1.ps1 , but the helloworld1.ps1 script call another script.
here’s the code of helloworld1:

 & "$PSScriptRoot/helloworld2.ps1"
 Write-Host 'Hello from 1st File.'
 printHello

And the helloworld2.ps1 scripts contains this one line only:

function printHello()
{
Write-Host 'Hello from 2nd File.'
}

BUT, when when pipelines triggers, its run the Helloworld1.ps1 and print its 2nd line and then failed on 3rd line throwing the error:

 | The term 'PrintHello' is not recognized as a name of a
 | cmdlet, function, script file, or executable program. Check
