Powershell exit does not stop script from running - powershell

Question

I'm running a Powershell script from a Powershell window.
Inside this script, I'm trying to connect to a service, and wish to stop the script if the connection fails on an exception.
I'm catching the exception but the script refuses to stop, but continues on.
I tried checking error output using **-ErrorAction** and **-ErrorVariable** and many other things.
But the issue is the script does not stop. The script is saved in a .ps1 file and I just run it from the shell windoe".\script.ps1"
Here's the code:
Write-Host "Attaching to cluster and retrieving credential" -ForegroundColor Gray
if ([string]::IsNullOrEmpty($clusterrg) -or [string]::IsNullOrEmpty($clustername)) {
Write-Host "Failed to attacth to cluster. Parameters missing." -ForegroundColor Red
Write-Host "Use -clusterreg CLUSTER_RESOURCE_GROUP -clustername CLUSTER_NAME in the command line`n" -ForegroundColor Red
Exit 1
} else {
try{
az aks get-credentials --resource-group $clusterrg --name $clustername
Write-Host "Done`n" -ForegroundColor Green
} catch {
Write-Error $Error[0]
exit 1
}
}
Would appreciate any help.
Thanks you!

You are using the Azure CLI, not the Azure PowerShell commands. So try/catch as well as the common parameters -ErrorAction and -ErrorVariable are not supported. You have to check the $LASTEXITCODE variable for errors.
az aks get-credentials --resource-group $clusterrg --name $clustername
if( 0 -ne $LASTEXITCODE ) {
Write-Error "Azure CLI failed with exit code $LASTEXITCODE"
exit 1
}
You can find possible Azure CLI exit codes documented here.
