Azure DevOps task inline script with powershell does not fails the task on error - powershell

Question

In the Azure DevOps release pipeline I run Inline Script as part of the Post Deployment Action of Azure App Service Deploy task (Task version 4.*).
The inline script looks like this:
powershell -NoProfile -NonInteractive -ExecutionPolicy Bypass -File UpdateCSP.ps1 -ApiUrl "$(API_URL) $(API_TESTING_URL)"
powershell -NoProfile -NonInteractive -ExecutionPolicy Bypass -File GenerateVarsJs.ps1 -ApiUrl "$(API_URL)" -IdamAuthServerUrl "$(AUTH_SERVER)" -IdamClientId "$(CLIENT_ID)" -TestApiUrl "$(API_TESTING_URL)"
One of the scripts was hard terminated (by invoking Throw "some error text") command. The error was written into the task output but the task itself succeeded.
Hard terminated powershell script returns error code 1. Therefore my expectation was that script failure would also fail the task.
I would need the task to fail in case of script failure (nobody is checking the output of succeeded task). How this could be done?

Answer 1

I carried out a simple test. And it worked fine.
I have a simple command throw "This is an error. in the .ps1 file. I call the script in the Post Deployment Action of Azure App Service Deploy task:
The task failed as expected:
However, You can have a try using logging commands #vso[task.complete result=Failed;]Failed in the .ps1 file to manually fail the task. See below:
Throw "some error text"
Write-Host "##vso[task.complete result=Failed;]Failed"
Or You can try using [Environment]::Exit($exitCode) after the Throw command in your .ps1 file.
Throw "some error text"
[Environment]::Exit(1)
